This week's tip is from texastintchick ~
After you have finished tinting your customers car and have handed them thier reciept and warranty, also hand them two (2) business cards. Explain one is for them so that they will always have your number handy for future reference, the other is for a friend or coworker they may know that they can refer to your business. Many times they will ask for several more so always have a hardy supply. The cheapest (and maybe one of the best) form of advertisement is word of mouth, next are business cards!
