Herbal Remedies will rip you off and it's $100 more if you want to choose your own caregiver. I think that means $300+.
Their dispensary is pretty crappy too. It's only a couple of jewel cases full of pre-packaged 8ths, grams, halfs, etc. Also, they charge more for "tops" of plants. I saw in another review it was like $325 for 17.5 grams for a "top" of a plant.
Look on weedmaps or legalmarijuanadispensary.com. There's a few reviews on this place. You can get your card here, although there's cheaper places, but I definitely wouldn't shop here.

Also, at this place they don't make you sign a contract to keep their caregiver for any amount of time. Other places that have a little foresight do this. So, I would take advantage by letting them assign your caregiver for the $100 discount and then immediately file a change of caregiver form with the state and notify Herbal Remedies in writing via certified mail. I'd wait a few days until your paperwork has been sent off, or better yet, I'd go somewhere else cheaper. Pick up a Westword and turn to the back!!
