I stopped my online order at check out when I was being charged for shipping on a 300.00 item and the tax they charged me was 3.00 more than my city tax code collected.
I went to Amazon got free shipping and was charged the correct amount of tax.
10 minutes later these guys called me and tried to sell me the product. They then emailed me asking me to buy the product and gave me a 12.00 coupon but still charged me shipping and the wrong amount of tax.
Approach with low expectations and be prepared to not understand there language.
