Here's some perspective - we're doing a charity event and we don't want our cars damaged if possible. The cost to buy this stuff is less per head than any smart repair or otherwise. I decided (and mentioned previously) that I thought it better to pass any discount to the charity rather than personally profit. They have donated more than 10% of the order and provided another roll for free to us. They are sending some of the tape from California for the same price as quoted for local delivery.
Time to put the calculator down and see this for what it is. I'm very busy and spent a lot of my own time liaising with the company. Anyone who wants to step in and organise these things please be my guest.
