I've also booked a new car rental reservation for my arrival tomorrow. I checked and it seems that Avis takes Sears credit cards. I think Budget used to be the company that accepted this card, but both Avis and Sears websites say that it's Avis that accepts it now. I didn't prepay this reservation so if it doesn't work out I haven't lost any money. If the rental doesn't work out, one of my sisters has generously offered me a backup plan. I'm touched and very grateful for her offer of help.
I used to carry both a Visa and a MasterCard but dropped the Visa a few years ago. There's definitely an advantage to having more than one major credit card... but at the same time, having more than one could possibly open me up to being defrauded on the second card. Having had this second set of fraudulent charges on my card and having had my identity stolen, I'm feeling paranoid that it could happen again.
I'm looking forward to going to Edmonton tomorrow and seeing my sisters and their families and my friends. Hopefully everything will go smoothly while I'm there.
