Got a mid to high price product? Want to keep your costumers coming back? Here is a very friendly way - send them personalized greeting cards! (REAL mailed cards, not ecards, also include a personal message from yourself, dont make it an ad) Im doing it for my electronic cigarette website and will do it with other retail sites Im working on. It costs $3.50 to send 1 card on cardsremembered.com and as low as $2.50 if your sending a bunch. Its worth it, the customer will think your the best, what other company send them cards? If your making $30-40-100 or more per sale, it wont make a big dent in your profits and the investment is likely to pay off. Another perk is they may talk about with there friends "lol, I got a halloween card from bla bla bla"
