For lower volume ecommerce sellers in the UK, choosing between traditional postage stamps and online postage depends on order frequency, parcel weights and how much time you want to spend at the post office. Stamps offer simplicity for very occasional sales while online postage usually provides better value and tracking once volumes increase.
This guide explains the practical differences in cost and convenience, with specific steps to help you decide which method suits your current fulfilment needs and when it makes sense to switch approaches.
Understanding the Two Options
Postage stamps are purchased from post offices, supermarkets or online and affixed directly to packages. You pay the standard rate shown on the stamp and drop the item at a postbox or counter. Online postage involves buying labels through Royal Mail’s Click & Drop, other carriers’ portals or integrated ecommerce platforms. The label is printed at home or in your workspace and includes a barcode for scanning and tracking.
Both methods deliver to the same Royal Mail network for standard services, but online postage unlocks discounted rates for account holders and removes the need to queue for weighing and payment at the counter.
Cost Comparison for Lower Volume Sellers
Stamps usually cost the full retail price for letters, large letters and small parcels. For items under 100 g, a stamp might be the cheapest route if you already have the correct value to hand. Once parcels exceed 1 kg or require signed-for delivery, the price difference widens because online postage often applies volume-based or account discounts that reduce the per-item cost.
Lower volume sellers sending fewer than 30 parcels per month frequently find stamps convenient for the first few sales. However, printing labels at home avoids the risk of using the wrong stamp value, which can lead to items being held or returned. Always weigh each order accurately; even a few grams over a weight step can increase the price by a noticeable amount. Rates change periodically, so check the latest prices on the Royal Mail website before buying stock of stamps.
Convenience Factors in Daily Operations
Buying and applying stamps requires a trip to purchase them or keeping a varied stock at your workspace. You must then visit a postbox or counter during opening hours. Online postage lets you create labels at any time, including evenings and weekends, and drop completed parcels at a local post office, business collection point or arrange a pickup if volumes justify it.
For returns, online postage allows customers to print their own labels in many cases, reducing your administrative work. With stamps, you often need to supply a prepaid envelope or instruct the customer to buy their own postage, which can slow the returns process and increase the chance of disputes. Tracking is included automatically with most online labels but usually requires an additional stamp or service when using ordinary postage.
Practical Steps to Calculate Your Best Approach
- Weigh ten recent orders and note the exact weight and dimensions of each.
- Check current Royal Mail price steps for both stamped and online options for those weights.
- Factor in your time: calculate how long a post office visit takes including travel and queuing.
- Estimate monthly volume for the next three months based on current sales trends.
- Compare total cost including any printer ink or label paper for online postage.
Repeat this exercise every quarter as your order profile changes. Many sellers start with stamps for the first 10–20 orders per month and move to online postage once they can predict weights more consistently.
Handling Returns and Inventory Impact
Returns affect both methods. With stamps you may need to supply a returns label in advance or reimburse the customer for postage costs. Online systems often integrate returns labels that are charged only when used, helping you control expenditure. Keep a simple spreadsheet recording returned items, associated postage costs and restocking time so you can see the true cost of each channel.
Accurate inventory records prevent over-ordering stock because of lost or damaged returns. When using online postage, the tracking data can be imported into basic spreadsheets or free tools to update stock levels automatically after delivery confirmation. This reduces manual counting errors that sometimes occur when relying on stamped post without tracking.
When to Switch from Stamps to Online Postage
Consider switching when you regularly send more than 15–25 parcels per month or when more than half your orders require tracking for customer confidence. The time saved by printing labels and dropping at a convenient location often outweighs the small additional setup cost of a thermal label printer for consistent sellers.
Test the switch with a single month: buy online postage for all orders and compare the total spend and time taken against your usual stamp routine. Adjust your choice if your product mix includes many lightweight items under 250 g, where stamps can still be competitive. Remember that carrier terms, fees and available discounts change; always verify the latest details directly on GOV.UK, Royal Mail or your chosen platform.
Integrating Postage into Your Overall Fulfilment
Choose one primary method and document the process so anyone helping with packing follows the same steps. For mixed approaches, keep separate records for stamped and online orders to analyse which performs better. Combine postage choice with sensible packaging selection to stay within lower weight bands where possible.

Frequently asked questions
Is it cheaper to use stamps or online postage for small ecommerce orders?
For very low volumes and lightweight items, stamps can be marginally cheaper because you pay only the exact retail rate. Once you send more than a handful of parcels or need tracking, online postage usually offers better value through account discounts and avoids wasted stamp value on incorrect weights.
Do I need a printer to use online postage?
Yes, you need access to a printer to produce labels at home. Many sellers start with an ordinary inkjet printer and plain paper, then upgrade to a thermal label printer once volumes make label costs and speed worthwhile. Printing at a local library or print shop is possible but reduces convenience.
How do returns work differently with stamps versus online postage?
Stamps usually require you to provide a prepaid returns envelope or ask the customer to pay postage themselves. Online postage lets you generate prepaid returns labels that are only charged when scanned, giving clearer costs and easier tracking of returned stock back into inventory.
When should a new ecommerce seller start with online postage?
Begin with stamps while you establish product weights and order frequency. Move to online postage once you can predict typical parcel sizes and when the time saved by printing labels outweighs the effort of buying and applying stamps. Reassess every few months as sales grow.
Can I combine both methods depending on the order?
Yes. Many small sellers use stamps for very light or local orders and online postage for heavier or tracked shipments. Keep clear records of each method so you can review which delivers better overall cost and customer experience after a set period.
