Watchfull was kind enough to suggest producing car stickers to get the word out there!Various different kinds exist - car stickers, vehicle vinyl, bumper stickers and window vinyls / window stickers.Window stickers (well vinyl) are probably the better option). Does anyone know any suppliers? I will look around. Once with a design it is either buy an batch order of 100 or 1000 (whichever is the Minimum Order Quantity, MoQ) with a waiting list to buy new batches or one of those websites where people can individually get one (likely most expensive per unit). How much would you be willing to pay for a sticker/vinyl (with P&P)? Depending on unit cost as to whether it is something that could be given away or bought at cost (with P&P), hopefully with a view of not charging anyone from IPSWI other than P&P... sending multiple once could create some savings too. What size? Any design ideas? A large rectangle, circle badge, square? Perhaps a few full-width designs?Any other promotional ideas? Perhaps vinyl on car bonnet, side door or boot? Just brainstorming ideas for now!
