I don't mind paying for postage, as you say it's to be expected. I'd much rather pay for postage than do the great B&M hunt. I wasn't complaining about paying postage, just saying that it doesn't make sense to force people to buy extra stuff they don't want just so they can give less money to CO. CO surely loses out in that scenario because they take less money, post double the number of items at their expense, and they end up with fewer items in stock to sell. Not to mention the fact that they'll have no idea how popular certain products really are.
The conversation at CO will be: "These Peppa Pig single figures are selling really well, in fact we've almost sold out, we'd better make some more!"
When in fact, if they just reduced the cost of postage by £1 they'd take exactly the same amount of money and they wouldn't have incurred the added cost of producing and sending out all those Peppa Pig figures.
