Got a message from my bot when I logged on stating:
Dispenser 65 (VIP): Accepted: Lieutenant Bites #3000, 3.55 credits. Your shop has 955 slots left.

I am currently buying Bites for 2.33 and have been for the past month.

I have edited your credit, there were two trades that you paid extra. There was a bug that caused items to be counted 2 times (Any Hat + specified hat). This bug is fixed.
