Actually 1 thing which would be a great addition to OcUK is a points system for people who shop at the store a lot.
For things you buy of a certain value you get points in accordance to how pricey the item is, these points can be exchanged for things from OcUK on selected goods, things like games, controls for consoles, certain software etc. So the people who spend a lot of money at the store get rewards for being customers and not only that, new customers feel more obligated to come back shopping here to get more points and thus get free gifts in the future. So not only do customers benefit from the promotion, OcUK does as well.
