wait til safeway or other grocery store has a special where when u buy $50 worth you 'll get back 10$ off....also hope that they have a good gas special offer..then use the amex preferred or some other bonus card at supermarkets...
don't forget that you can use the movers 10% off coupon up to 5k in purchases..and just split up your order..
u can use the coupon online at lowes..going thru whatever portal that will help you out the most.....in my experience most online shopping portals have allowed gift card usage when going thru the portal(at least american & united has)..and using the 10% off going thru shopping portals has always worked out for me...
