I've had a HD Visa since 2002. Same ++'s as everyone above, no negatives. I always pay off the full balance each month. I use it for big purchases like appliances, truck tires, etc.
I was on vacation last year, found my SE6 out of state. After negotiating to a good bit below MSRP, they wanted $1,000 down to hold it for a week until I could get back up there. Used my HD Visa to hold it!!
I usually request my Chrome dollars a month or so before our big summer trip. I use the $25 vouchers to buy HD T-shirts all along the way. Even tho' the rule is use your HD Visa for any amount over the voucher, I've found that some dealerships will take $3 or $4 in cash with a $25 voucher for a HD shirt.
On our summer trip, all food, gas, lodging, etc. go on the HD Visa, then we pay it off as soon as we get home. Same for Christmas shopping.
It is the only credit card we have. I often wonder if after years of paying off the balance each month and never, ever paying them any interest, will they cancel me?!?!?
