Just found an incredible deal on CO2 refills in Denver, thought I'd pass it on since the massive price-hike at Red Comet ADX went through.
Way to Grow (301 57th Ave in Denver, they also have locations in Boulder, Fort Collins, and Colorado Springs, but I've only done refill at the N Denver location so probably a good idea to call your local location to confirm they do refills), an "Organic & Hydroponic Gardening" operation, offers 20lb swaps for $6.99, and will also refill any size tank for $6.99 (sounds like they generally have you leave the tanks and give you a pick up time later that day or the following day, but if you happen to come in when the guy is doing the daily tank refills you can wait and take yours home then).
Dropped off my two 10lb tanks earlier this afternoon, was told they'd be ready in an hour. They were ready to go when I came back to get them, and I was out the door quickly.
