The cartridge prices I've been finding here in OR are about $15 - $20 ($12 - $14 on sale days) for fruity flavored bullshit carts, $25 - $35 ($18 - $25 on sale days) for live resin carts, and around $50 - $80 ($45 - $65 on sale days) for rosin carts. At least that's what I've been seeing the last couple of months.
When I was in an illegal state, I just stopped buying carts all together if they didn't come from someone I trusted, was still in factory sealed packaging, and I could verify that it's a legitimate brand that I can look up and see their test results...So, in other words, I rarely bought any carts ever when I was in Texas.
