I get most of the satchels from AP's website, sometimes in a local AP business centre. The other day had to duck into one of those newsagency + AP hybrid stores to drop off a few packages.
Whilst waiting for the fella to finish and while browsing around he asked if I needed any more satchels and I said nah have some from website on order. He said that's fine however it'd support the little guys if I'd consider buying from them in the future.
Seems obvious but never occurred to me before that non full AP stores the owners can skim a bit off the top. Does anyone own one of those shops or know how much AP sells those express satchels (S/M/L) in 10/pk to the store for? Always been curious what the mark up on them are.
I'll take a guess; somewhere between 10 and 15%. Hopefully someone with more knowledge can give you a correct answer.
