Here's the price breakdown, the discount that he can offer and the quantity of people required. I have to admit at being shocked at the price for just the tips!
Backbox on its own £522 (inc VAT)
Carbon or Ti tips are £560 (inc VAT)
Sound Kit is £567 (inc VAT)
No he can do a 10% discount if 3 people are in, with free shipping on them. Alex @
AKS Tuning is the person I've been getting these prices and is prepared to do this.
