Tattoo Merchandise Shop review for Hulk Bundles Quantity Breaks

User beware! I tried this app and it it APPEARS to work but does not. The discount was present all the way through the checkout process but once the customer clicked the "Pay now" button the app would only sometimes apply the discount. Customers credit cards would be charged more than they were quoted. I deactivated the app quickly but in the time it was being used, it had about a 50% success rate. Unreliable. Do not recommend.
