Had 2 gift certificates of $5, from rewards, and was able to redeem only 1.
Also prefer paying using PayPal but BookOutlet wants to store my PayPal info for automatic payments. I have never encountered that with purchases online hence ended up using a card I don't normally use for other purchases. Not happy that I as the consumer do not get a choice of whether I would like to store my card with you or not! I do NOT mind at all typing it in each time, rather than having it "safe" with online merchandisers.
