I had an interesting experience today...
I purchased 4x $200 Visa cards + 4x $50 Amazon cards. It took forever to get the purchase to go through... they said they needed approval from the store manager and since he was out had to call the district manager. They mentioned that purchases above $500 or $1000 (got conflicting information) required this additional approval.
While they were doing this they were carrying around a 3-page sheet titled "Office Depot and Money Laundering with Gift Cards" with all the new rules they were supposed to go by.
