Chris i already know your prices are great for the quality of juice you provide, i have placed two orders with you so far and never been dis-appointed. This is just an idea of a reward system for loyal customers. I have seen this on other sites as well. example if you purchase 30ml of juice that 30ml bottle gives you like 10 points or whatever. You can redeem your points for a certain amount of juice like 40 points = 30ml of juice.... Just a suggestion and have you thought about implementing something like this?
