Hi:
I was here last yeat, but didn't post. This will be my seventh BF. My best tips? Get there early, 3:30 am is not too early. Bring a friend, coffee, a small chair, (You will have to ditch it about 45 minutes before the store opens, that's why you need a friend to hold your place in line.), and all your sales circulars. If you live in a cold climate, dress warmly and bring a hat, gloves, scarf and ear warmers with you. A light blanket will not hurt either.
And the ulitimate tip, I learned last year from my best friend, use the blanket, chair, coffee and circulars to make friends with the people in front and directly behind you in line and they will glady use them and hold your place in line, while you wait in the car, nice and warm! LOL
