Well, I was hoping that St. Patty's Day might show us some decent sales but I haven't seen this to be the case on the vendors I'm watching. I gave up watching a whole bunch, only the ones I have a a possible personal interest in.
I guess the next possible sale date will be Easter (April 4), but that might be after the USPS ban goes into effect or dangerously close. And lots of vendors have expressed they will stop taking new orders on or before March 27.
Boy am I glad I came back to ECF in 2019
I did find a couple Going out of Business sales from a couple vendors I never heard of. But the base price is so high that even after 20-30% off the prices are still higher than the well-known stores or the same.

Tack on shipping & the fact that they are unknown, you may as well just buy regular price from known vendors.
