Best car cover you use for your mopar?

Well i contacted covercraft about their custom form fit indoor car cover, while emailing them back and forth they ran a sale and had them for $460 with free shipping, well i got a quote for alterations to accommodate the go wing and was quoted $529 + tax with free shiping. I told them that i would be fine with that, they were going to get a pattern together and get back with me, well i got a email yesterday and they told me that they had a pattern finalized and the extra material was going to be $100 more than the $529 i was quoted but they would split the difference and only charge another $50 more. I told them i wasnt interested in it for anything over the price i was quoted. I mean why bother quoting me when they had no clue, i specifically asked to price the cover including the alterations. I told them i would take the cover for the $529 but not any more over that, havent heard back from them yet lol
