American Express has another Sync offer and it is $10 off $50 at Lowe’s which means you could save up to 20%.
The best bet for gift card churning is to buy $50 worth of BP (not listed on Dan’s Deals) or Shell gas cards and resell them at 90% according to Gift Card Granny and pocket the 10% spread.
While the percentages are double digits, in actuality it is only $5 profit. All of this profit has actually added up where it paid for my American Express Starwood Preferred Guest annual fee.
