edit: They did have a issue with CC details leaking, but they denied it and then it took 'em ages to upgrade their system to a more secure one. I never had a issue with my card, though.
I'm on Priority 2. (£16 pm. 2 games out at a time. Unlimited rentals. 1st class postage envelopes.)
Below is a list of all the games I've rented.
If you cba, you can check the dates of dispatch for the AAA games, and you'll see the vast majority, if not nearly all of big releases, were sent out upon their initial release date. The ones that weren't, I didn't have them down as launch rentals as I wasn't *that* interested in them, (stuff like CoD, Battlefield) or stuck them on my rental list only after they were on in stock/0-3 day dispatch/free rental status.
According to their account page, I have saved approx £2,072 since joining in late 2014.
