I’ve food luck with th quality from PSA, but the shipping is absolutely horrendous. I’ve experienced it taking weeks to receive products from them multiple times.
I don't know when the last time you ordered from PSA, but they have drastically improved their shipping times. It took less than a week to receive my rifle kit, and less than a week to receive three different ammo orders.
I know they used to have a very poor reputation on shipping, but I think they've really addressed that issue in the past 2-3 years.
You may want to give them another try.
PSA was awesome on my buy there this year.
