Hi ive used them,
If your just after the latest releases,they are not very quick.It is best to have at least 30 to 40 dvds on your selection.There is also a tendancy to send older releases recently added to your selection ahead of new releases that have been on your selection for ages.
How this promotion impacts on the stock levels,will also determine the speed of turnaround.
In the five months that i had membership,the family recieved 70dvds on the 3 at home package.
Also please note Tescos is basically a shop window for love film,all of the operation is through lovefilm.
