I got my AWU3 from CEX. (UK buy/sell/exchange store not entirely unlike GameStop in the US). It was A grade so absolutely mint.
Traded my series 7 and added cash from the sale on eBay of 64GB DDR5 that I wasn't using.
Enjoy.
I didn’t know about CEX, and I just noticed that they sell A grade Ultra 2 more expensively than I paid for a new one on Costco.
Very good price for the Ultra 3 though.
