Why didn't you just make the buyer pay more for the shipping?
i didn't realize this until i have shipped it. so i could not enforce that. and i would not have anyways, it isnt the buyers responsibility to pay more than the amount of the bitmit order. this is a glitch on their site and i wont charge my customers more than the agreed on price after an order is already shipped...
So let me get this straight:
You listed your items, in 1 listing, created the shipping price, and once someone bought it, you shipped it, but you just noticed that shipping prices were super high. How is this bitmit's fault?
I'm pretty sure that's not what he's talking about. You can sell multiples of the same item on BitMit (as in, you can sell x qty of an item, and buyers select how many they want). I think OP is saying shipping cost did not adjust for the buyer ordering more than one of an item using the quantity function. I've never dealt with selling multiples of the same item, so wouldn't know.
Sites like eBay usually have a tool to input shipping costs for multiple items (since it's often cheaper per item to ship multiple units of something instead of one). BitMit, OTOH, does not have this feature, so it's reasonable to think if shipping price is set to, say, .1BTC, and a buyer orders four of the item, they'd pay .4BTC in shipping, not .1BTC.
