SPD Split Payment & Deposit

This app will NOT work to split the cost for customers that want to use two credit cards or one credit card and Paypal. The reason it won't work is that it splits the total cost that is in the cart, BEFORE shipping or taxes are added to the total. For instance, if your customer has $200 worth of merchandise in their cart, this app will split that for them and lets them choose how much to put on each card. But then let's say that shipping is $10 and tax is $14. That makes the final total $224. The additional $24 is not included in the split and therefore not collected. I've tried to explain this to them but they don't get it. I don't understand all the reviews that love this app unless these store owners aren't charging shipping or taxes to their customers. Nice concept, but worthless.
