Buying your costume from the local drug or grocery store was a pretty common thing back in the day. However, since the advent of big box stores, not so much. There's still a mask or odd vampire fang, but what's really great about these stores during Halloween is the random neat stuff they'll have. Walgreens has always been a haven for Halloween. Every spooky season it's a must stop shop and I'm sure many of us are taking a swing through their seasonal aisle while picking up prescriptions and imagining when it'll be covered in pumpkins and skulls.
