SPD Split Payment & Deposit

I would like to restrict split payments to draft orders only and not have the button displayed on the checkout page.

Seems like a good app but if you want to use a coupon code then it won’t work. coupon codes are a must for my store so sadly I can’t use this app. Customer service was great though, by chat they quickly confirmed this is is an issue caused by shopify’s limitations.

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.

This is only 5 days free trial not 7 days as it states in the app store.
If even this can't be accurate, how will the app work properly? Big red flag!
