I didn't bother price-shopping too much back in 2020, so this'll be a little ot, but ............
You might wanna spend some time on youtube at the same time you shop around. Lot of self-professed Consumer Reports types there do vids comparing Racks, Benches, Bars ... you name it. Just about anything you might consider for a garage (or any other place in the home) gym has been reviewed and compared with competing companies.
While you're thinking about Iron, you'll probably want to think about flooring too. Some of the gym equipment companies sell this, but check out the places that sell stable mats too. You don't need to cover the whole floor, but the areas where a loaded barbell or dropped dumbells are gonna land pretty much need some cushioning.
If you're not doing OL or OL style assistance exercises ... and if you can resist the appeal of just throwing weights around for the fuck of it ... get cast iron plates instead of bumpers to save money. In some cases some bars or other equipment have limited sleeve length, and bumpers are thicker than cast iron of the same weight.
If you order online rather than acquiring locally, DO factor in shipping costs. If 2 different online places list similar stuff, similar quality, for similar prices, the company within 300 miles will cost a lot less than the company 3000 miles away. Ideally a place you could drive to yourself, but that's not always possible.
Lastly, if ordering online be a little wary of things indicated as "back ordered." Sometimes they will ship when the website says they will ship, and sometimes they go way past the "eta."
Rogue offers great variety and quality for "ouch!" prices (though a few places are pricier), BUT Rogue's website may be the best place to feel your way around the online market if you can't find what you want locally. They have charts showing the diameter and thickness of each weight plate they sell, if you dummy up a purchase in the shopping cart there is a calculator that tells you what your S&H would be ... it's an education even if you wind up going with someone else.
