My Tarts have become very popular and I am considering selling the warmers. Which do you find are the most popular the combo warmers, plug ins, electric or tea light? I personally like tea light but that may not be everyone. If I do get electric I want to make sure they have enough wattage etc. And curious the best places for wholesale pricing, I've looked at JD Wholesale they are the only ones I find with good pricing, but they are a bit boring looking.
