Outlets, I trust my regular brands and look for items that have discounts

REI tends to have a lot of good holiday sales. Even if you don't have a local store, all the sales are online too. There's also a few geartrade subreddits, lots of gear trade/sale Facebook groups, and ebay

32 Degrees clothing line are affordable and will do the job for colder climates.

Facebook marketplace, ebay, and poshmark are my go-tos these days for buying athletic clothing. Janji, Lululemon, PrAna, Smartwool, Outdoor Research are all great durable brands that are way more affordable secondhand.
