Hopefully I'm mistaken of the exact products your trying to sell or maybe I'm just really bad at math but Im not too sure if it's a "pretty good deal"...... I took advice from your other listing (8g biocube for sale) and did a quick 30sec search for the JBJ 3gal Picotope tank and AC70 to see how they look right from the manufacturer and came across this:

Good luck with the sale
