I have good them to credit basically every week now.

Here’s what I do:

• use Chrome
• clear all cookies
• Go through eStore, do the order, checkout
• clear cookies, go through eStore, amend order, checkout again as quickly as possible. Repeat this.

It’s worth noting that if you do an order for £40 to hold the slot and it tracks this order, then you will only get the points based on the £40, not whatever your final order value is, so if you do this worth pushing first order up to what you expect to spend.
