Al, Double checked PakShak website, Ranney takes checks. Go to the main page and hit "Payments and Shipping" it tells you the procedure. I knew he had to at least take checks.
Good to start with a full set of towelsone for removing each product, you don't want to mix them. If you're washing you want one for that, claying (can be shared with wash) compounding/swirl removing, Zaino or whatever. The small ones are great for windows and the interior. They come 16x16 and 24x24 I think.
I purchased 8, four of each size and need more.
According to the website he's also going to offer a big 36x25 waffle weave towel. The waffle weaves are nice because they absorb more liquid, making them better to use when drying.
