This is just one of the many reasons that I don't buy on line. I think it's faster to go to the local parts store and get what I need. You may get things cheaper but if you have to return it then you're that much farther behind. And last I believe in supporting my local business and help folks to have a job. I don't use self check out or bank online.
I'm glad you are such a model citizen... I was buying from Autozone because they had the best prices and a few places had to order them. 3.69 a plug one day 7.29 a plug the next. I don't think so.
