just took a look, I think they are far too late to the internet selling game to be useful, they have too few items listed to re-draw lookers and the prices are high-ish for used items.
Even though it isn't so much fun as it once was, ebay is still the place to draw enough lookers to get a sale.
And my pacific NW facebook quilters group has a selling group and I've found and sold many things there over the last 5-10 years of cutting down stuff, including all my machines but the two I use all the time.
I've looked at the facebook selling groups like destash a number of times but the volume moves the page too fast and again, hard to get the eyes needed to buy something specific. Although the Kaffe group seems to sell out everything. If there is a Tula group it probably does too.
