I just went to site and can't get past the enter and update zip code window--- must be overloaded now.
EDIT: Finally discovered that the site was using an old, outdated T-Mobile coverage map that erroneously states that there is no coverage at my zip code, so the site was actually checking for coverage rather than for figuring out taxes. So I put in a big city zip code and the order went through while allowing me to use my real zip code for mailing and billing purposes. Paid 1 cent with Paypal.
Nice!
email confirmation received.
Nice that they let you opt out of auto pay on the checkout page.
I paid with PayPal and can verify that no automatic payment agreement was authorized (unlike visible deal where you had to go in and cancel future payments).
I wonder if Mint was hurt by its zip code/tax calculator rejecting many applicants, including myself and E_Z. I contacted Mint CS and said it appeared that the zip code/tax calculator was actually using an old, outdated T Mobile coverage map that was rejecting zip codes where T mobile service has been available for many years. CS got back to me quickly, after I had already figured out the problem and placed my order, and said to put 00000 as the zip code to see if that worked. Curious that Mint had a tax calculator, aka coverage checker, running on a free or 1 cent promo plan in the first place.
