Newegg.com is offering a bonus $10 gift card with the purchase of a $50 Hotels.com card on their site. Up to 2 times.
I don’t really see any resale value in Hotels.com cards because most sites don’t accept them for resale or only offer deeply discounted prices to buy them. This is a good deal is you use Hotels.com. I would also advise using a cashback portal for Newegg where you can earn an additional 1-1.5% cashback.
