American Express has 10% back offers at Staples and Lowe's that I just found out about. So I got 500 from Staples and 1,000 from Lowe's, which were the limits. I think I'll use my Chase Ink to get 5x points at Office Depot for the rest ($3,500 - total will be $5k, not 7k like I was thinking).
Wouldn't the 2x Chase portal at Staples probably not track since it's a gift card? Thanks,
