I plan on buying Amazon gift cards to fulfill a spend requirement for 75k MR points offer on an Amex Plat Business and then using them personally. We buy tons of things each month on Amazon and won't have any issue spending the gift cards quickly. Any pitfalls here? Does Amex accept this as spend requirement to get the bonus offer? Any reason to wait until the end of the 3 months or should I just do it now? Thanks for the help. Search didn't turn up a simple answer to the question that I could find.
