It is pricey to do but i had this exact same conversation with Chip at Laurel, better off to buy 3 column than retrofit single columns. I Have 2 sites, one i have Electronic with
Credit Card, the other is newly acquired and does quarters only site wide, needless to say im upgrading a bunch of stuff. At the site with Electronic and
Credit Card my
vending sales have at least doubled since installing the
credit Card options. Needless to say the newly acquired site will be upgraded as well to full electronic with
Credit Card. We dont get rich off
vending, but it does keep the customers on the lot longer, but more importantly they will notice the upgrade and know that you are putting something back into the business. My customers are always asking what im going to do next, i usually ask them if they have any ideas.
