Secret sale?

Is there a secret sale at Lettering Delights? I found several graphics sets on sale for 0.50 each! Here are just a few pictured:

I checked my usual sources (email and FB) and saw no posting about this. Click on the image to see the results yourself - scroll down until you find the graphics. So if you have some graphics on your wishlist you may want to go through it to see if any of them are on sale.
