I'm 47 years old and I NEVER went to a BLACK FRIDAY sale until ... this year! I thought "those" people were crazy to get up and go stand in line for a sale. Let me tell you, "those" people are fun and friendly if you are standng in line a Joanns! I got FANTASTIC prices on their snuggle flannel; I was making some baby blankets at the time. They handed out $10 gift cards to the first 100 people in the store and it was a fun time had by all!
They did have sales on machines and other "big ticket" items like the crafting tables, etc.
As for a serger - I purchased my Brother serger from Amazon - free shipping around $200.
