So for a squat rack, you probably want this. It's way better than a $300 power cage has any right to be.

Benches are pretty basic if you just want a flat one and aren't benching super heavy. I'd recommend the AmazonBasics if you can find it, it's not listed for some reason. But otherwise I'd grab a $50 starter bench and not worry about it, by the time you need something nicer you'll know more about your particular needs like a wide bench, adjustable, fat pad, etc.

For a barbell and plates, you're honestly probably best off hitting up Dick's Sporting Goods for one of their $300 starter kits. Ordering is really just going to kill you on shipping.

I paid 250 after tax. Shipping was free due to amazon prime.

This is the rack in question. It sold out within ten minutes of being up?

Do you have a camera placed to watch where the UPS people are dropping off your items. Perhaps you're being porch pirated.

I haven't moved, but recently had a 145 pound "mistake" sent to my house. It was a full sized weight lifting squat rack.

UPS also had some girl, who must weight 85 pounds soaking wet, deliver it...and then she had to pick it up 4 days later (although I was able to help her with the pickup).
But beyond this mistake, Amazon service has still been pretty solid.

If you want the "best" cheap power cage, there's a sale going on right now for the Fitness Reality 810 rack. I think you'll get way more out barbells + dumbbells than just dumbbells alone but it's really up to your training goals, space, and budget. Xmark makes good entry level barbells and there's also a 15% off sale on them right now too.
