Not the most straight forward but does work.
Very are currently offering 20% off your first order if you opt to pay via there Take 3 scheme which means you pay it off in 3 payments or in my case you can pay it off early as I did ask the question to very before I ordered if this was possible.
This method does require you to be a new customer to this type of payment and it does require a credit check. Also note if payments are not made when due you will incur other interest charges so make sure you pay it on time or pay it all off once you receive your first statement to close your account.
