I'm interested in buying a fairly expensive watch that comes with a 1 year mfg warranty and will use AMEX for the purchase protection and extended warranty. I have a few questions-
1. The purchase will be over $5k so I'd like to use the AMEX Business Plat, especially since I may keep this card past the anniversary. Or I may use my SPG Business since I like SPG points. Br it would be hard to argue that this watch is a business expense. Does that void the extended warranty?
2. There's a good chance I'll downgrade whatever card I use by the time the mfg warranty is up. If I use a Plat card now but downgrade the card to Green in the next year, will the extended warranty still apply as long as the account is still open?
3. Finally, I'm thinking of breaking up the total cost to multiple AMEX cards (initial deposit now, balance later)-- as long as al accounts are open still, will the extended warranty still apply for the entire price? Thanks.
