You know what, upon closer inspection of the products themselves for Farm and Fleet and TS, they seem to be the same product and maybe volume? I don't know why in the description of TS it says .35lbs as the volume.
TSC used to carry the 80ml tubes, but they recently stopped and now only carry the 30ml tubes and sell them for the exact same price!! I was so mad that they did that! Now, I buy my selenium gel at Rural King. I LOVE Rural King! Their prices (for everything) are just un-beatable! I really wish we had a RK store closer to us....soon, I'm going to try and see if my local TSC store will price match somethings like alfalfa and beet pulp pellets (exact same brand just $4-$5 cheaper at RK).
Yep, that's the right price! RK's selenium gel (80mL) is more than double the size for the exact same price as TSC and F&F. TSC and F&F only sell 30mL sized tubes.
You mentioned that you go through a lot of selenium gel....another option would be to buy it from Jeffers. They sell 80mL tubes for $9.99.....you do have to buy $50 worth of stuff before you can get free shipping, but maybe you could just stock up on selenium gel though...
