Hidden App Fee – Jamba Review

Sometime over the last couple of days the Jamba Juice app started adding a hidden fee for using it, it appears to be 8% of the purchase price and they include the fee in a line for sales tax. There is no where it clearly defined how much sales tax is and how much the fee is, I’ve never seen an app do this and it seems totally unethical
