So I got a spam Email from LiveAquariia.com (used be drsforstersmith.com), I do not buy fish from them but will get some driftwood, frozen food or sale items now and then. So I clicked through to the aquarium supplies sales and most of it was for things I would never buy. However, Polyfilters were on the list and I use them when I ship. These come in two sizes and I normally get the 8x4 inch ($0.343/sq. in) as per sq. inch it is cheaper than the 12x12 size ($0.347/sq. in.). I never use larger pieces and they mostly go into bags of fish I am shipping.
So I am smart enough to buy just the 4x8. I am not too dumb to have figured out the per sq. inch pricing. But the thing that really gets me is this. The different packs of the 4x8 are one, three or nine pieces. Some are on sale.
One is not on sale and it costs $10.99.
Three on sale for $24.73 or $8.243 each. For three of these you would pay $74.19.
Nine on sale for $84.10 or $9.011 each.
Who is going to be foolish enough to buy the 9 pack instead of three of the 3 packs? DOH!
