I don't think it's a specific Labor Day sale, but optics planet has the vortex razor hd 5-20x50 FFP at $1699, but is including a 250$ gift card. Also saw some other vortex models marked down. Can probably still google and throw in the standard 5% off coupon as well.
Check Camera Land. Ask for demo items. They usually sell at a pretty good discount. They may have a few scuffs and scratches.
If that bothers you. Do a search for Larry's break in procedure. It's pretty epic.
I grabbed one of the Athlon Aeres BTRs from Midway at $425 because that’s such a ridic deal o couldn’t help myself(from Midway because I didn’t realize cameraland had a ridic deal on them too). Now I’m thinking I want something with a 44mm objective for this large frame build. I’ll pass the Aeres to you sealed in box for $420 shipped.
