THE SOURCED NEWS
What do the figures say?
The British Retail Consortium’s September report covers the five weeks from 30 August to 3 October 2026. Total UK retail sales rose 1.3% year on year, below the 12-month average growth of 1.5%. Food sales grew 2.5%; non-food sales grew 0.3%.
Online non-food sales increased 0.7%, compared with 1.0% growth a year earlier. These sales figures do not establish that shops sold more units or earned more profit. They are a broad market snapshot, not a forecast for your shop.
SELLERBUNDLE PRACTICAL ANALYSIS
SellerBundle: give your own September a quick check
Look at orders, average order value and returns together. More revenue can still leave you short of cash if stock, postage or advertising costs rise faster. Compare similar weeks and note any unusual product launch or promotion before deciding what changed.
Pick your strongest product and calculate what one normal order leaves after product cost, marketplace fees, packaging, delivery and advertising. Include a realistic allowance for returns. That gives you a starting point for judging an offer.
SELLERBUNDLE PRACTICAL ANALYSIS
Test the offer before buying the stock
Try the numbers for a small discount and a bundle. A bigger basket helps only when the extra items and delivery costs leave enough margin. Use your actual fee rules; a percentage discount on the selling price does not reduce every other cost.
Set a minimum margin and a small test budget before Black Friday planning gets busy. Review results before increasing spend or stock. A national sales headline can prompt a useful check, but your customers and cash position should shape the decision.
