For those of you who hate getting junk mail in your email box, you many not know that while Amazon has their Prime Days this time of year, other places are having their sales too.
One of these is Blick Art Materials
They have massive discounts now for all types of arts supplies (in case you want to stock up for the Winter)!
Check them out. And also check on your local art supply store at this time - to make sure they all stay in business.
