This reminds me of my early shopping days using EBay, where it wasn’t uncommon for sellers to under-price their products so they show up near the top of the price (cheapest-most expensive) sort pile, and then charge an outrageous amount in shipping.

I’ve found that almost always (at the time), that the seller offering free or low cost shipping was usually cheaper.
