Hello there @kaelonR

can you add restriction on a non refundable items like : Commendation of the Zandalar Tribe
when i tried to buy the item and select the quantity of the item it Max out all and buy 250 without confirmation ,
i lost over 11K Time badges and cant refund them . open a ticket and the GM said he cant refund them >

Hi @gaveer,

The Zandalar Tribe commendations have a max stack size of 250, meaning you've bought one stack of these commendations.

While I sympathise with you, I don't think it's realistic to put restrictions on non refundable items. 99% of items sold by vendors in WoW are non-refundable. This means I would have to put a restriction and/or a confirmation dialog on the vast majority of purchases that players make. I think the inconvenience of limiting purchases or requiring confirmation on the vast majority of purchases outweigh the benefits of preventing the fringe edge case like this.

BuyEmAll by default does ask for confirmation if you're trying to buy more than one stack, but these commendations have a rather high stack count of 250 items per stack, which is why no confirmation was asked as buying less than a full stack is considered a trivial purchase in most cases. I agree that this one was not a trivial purchase, but I don't see a good place to draw a line on what is and is not a trivial purchase using the in-game data available. Best advice I can give you is to double check the amount you entered and the total cost displayed before clicking the "buy" button next time.
