Office max has them for $9My Costco only had the smaller 12 gallon ones. It’s probably better since I’ll be filling them with tools and hardware making them really heavy.
Yeah, my hydroponic bins do bulge a little but the top rim holds its shape well. Then again, if they break on me it's not a big deal.Used them for bleaching & acid washing rocks in the past. Now they do bulge out a bit from the water so I would in no way say use them as a ghetto sump, but they do hold water long enough to bleach things dead
