We're still new in the game, there are so many vendors out there, it gets confusing. I've been choosing who to purchase from based on the service I receive almost more than the price.
This is a new venture for me, but I'm not new to the world of business, I started in retail many years ago and still remember everything I've been told.
Second job I had, I was 15 (started working at 14 on a county permit, 25 hours a week) One of the greatest people I ever knew, probably could have been rich, but he preferred happy. One thing he instilled in me, the guy that came in to buy a $1.00 item gets treated the same as the guy who just spent $3k.
I called Fellers, needed a 6" roll of tape. The person on the other end of the line answered every question, offered suggestions and never made me feel rushed. Called back in for the next order, not huge, only around $500 or so, same thing, great service, offered suggestions, even went so far as to arrange for the items to come out of other locations, even though the location in Jax had some of the items in stock, just so I wouldn't have to drive out there. They could have saved 3/4 the cost of shipping having me pick most of it up, but said this sounded more convenient.
Dozen or so other big companies that will NEVER get my business, regardless of how big we get, because they treated me like a pest when we were small.
