Yeah, with small businesses I generally try to use cash only, or debit (I've been told they get less fees for debit than credit).
As for the main subject of thread, I think I might add Igloo to the list. I bought one of their inexpensive ice makers (it had some fabulous reviews) from an online vendor. Worked fantastic the first night I had it, didn't work the second night. Since then I've been trying to get assistance from one of their techs (per their customer service), but so far no luck in getting a hold of one.
Mom even tried calling them for me (I had authorized her and her phone#) and she keeps being told someone will call back. I figure if I don't get anywhere by the end of the week, I'll see what the seller has to say. The only problem is that the original box got thrown out, but I have everything else.
Might end up calling it a learning lesson of who to avoid in the future.
