Just bought a Liberty Fat Boy Jr. from Lowes. Their price was $1100 before military discount, They are only charging me $65 to put this 700 pound safe exactly where I want it in my garage! Yes, they do carry smaller Liberty safes and ya can't beat the delivery charge.
Look at Costco.com. They carry a big selection, have great prices and all include delivery. I bought a really nice Big Horn last year and couldn't be happier. Watch their website. They always have a couple model on sale at all times. I saved $300 when I bought mine.
Check out Heritage Gun Safes, very high quality. I bought one about 10 years ago after a through review of the competitors and bought a second last year. They typically have the ability to arrange in home installation. I did mine myself (with son and wife) with a pallet jack. It weighs about 2200 lbs, but the jack and some plywood were equalizers.
