Bet you're right.

Just a note. I think this is the postage that ebay advertise as 'Fast 'n free'?

Well, if you're a seller, you should know that the stand out bit I am seeing in there is FAST.

I realise that free means postage price is built in. It's still attractive as I don't have to do any mental sums to work out the total cost, but to be honest, it isn't as important on ebay as it is on some other sites such as aliexpress, where Chinese postage costs can add absolutely huge chunks to the total price.

If you offer fast 'n free postage, just be aware a lot of buyers may very well assume it is somehow faster than other, ordinary post.
