I never write reviews for apps. It has to be pretty spectacular for me to mess with reviewing it. MyConsultant is pretty spectacular! Makes checkout SO MUCH FASTER and I know its accurate (as opposed to me using the calculator and possibly pressing the wrong numbers...anyone else do that on the calculator app??). It breaks it all down for you and is very intuitive. The only thing I would change is the ability to calculate 2 different tax rates on the same order. (Food items are charged a diff tax rate than non-food and shipping). I also wish there was a way to program the shipping to calculate based on the order subtotal. My company charges shipping based on order size, so it would be nice if it automatically adjusted this for me. Not a big deal for me to change it on each order, but it would be handy if it was automatic. Still, this app is top notch! Well worth the money!
