It can be argued that my sale is a quicksell given the fact it went to a bot, but in this case the buy order was much higher than the others which are no more than 3.37 keys. I've also been trying to sell it consistently for under the average price for months without any success (before having it listed at 7.55, I had it listed slightly higher but I didn't keep screenshots, and BPTF snapshots don't got that far back)

Given these reasons plus the fact there's a seller at 8 keys on SCM, I think this is fair
