Has anyone come across Target's organic potting soil? I was at my local store this past weekend and noticed a 20 lb. bag in the garden section for only $7. The product isn't listed online, but it was definitely available at the store I was at. I know that any organic potting soil should be good to use as a dirt substrate for fish tanks. I'm just wondering if anyone has come across this at their local Target. I know that MGOCPM is already a good value at $5 per 8 quart bag, but that 8 quart bag translates to about an 8 lbs. The Target organic potting soil is obviously an even better value. Anyway, I just wanted to give everyone a head's up for future reference. I'll post a picture later to show you what it looks like. I would've picked up a bag myself, but it's too much for the 10g I plan on dirting.
