Finalised order and negotiated discount

I am really pleased as I am ready to order the wristbands now. I negotiated a discount from Adbands - I got fast delivery for free, worth £35, by agreeing to have their name inside the bands. I hadn't wanted to have this, although it is standard and you have to request in writing that it is left out. But I thought that it would be worth leaving the Adbands name inside, in return for the fast delivery for free. (Usually 3-4 weeks, now 8-10 working days). A saving of £35!! And they will arrive sooner, so I can start selling sooner!
