A memo went around Safeway and affiliated stores introducing a new POS limit of $500 per transaction on select retailer gift cards. The following brands are affected: Best Buy, iTunes, Google Play, GameStop.
From what I understand this limit is already in effect, and it affects all stores in the Safeway family, including Vons, Randall’s, Albertsons, Tom Thumb, Acme, Jewel, Shaw’s. The actual wording in the memo is $500 per 5 minutes, so even a nice cashier might not be able to let you do back-to-back $500 transactions.
Thanks to my friend Jamie for tipping me off to this
