I don't think $19.05 is outrageous. There are a lot of factors that go into the cost of shipping an item.
There’s a minimum charge, then there is the size of the box, the weight of the box, the delivery location, is it a residential address or business address, a residential address is always more expensive, insurance, most companies insure the item for full replacement value, and then there is the handling fee that most companies charge, this handling fee is normally around $8 - $10 per order. As you can see with all the additional fees and charges shipping can get really expensive. We try to ship as much as we can by US Priority mail. We shipped 5 Mars validators on Friday afternoon in a large $19.95 Flat rate Priority mail box, 2 to Texas, 1 to Kentucky and 1 to Florida, they were all delivered on Monday morning. Had we shipped them by UPS or FedEx it would have been almost a week to get them delivered. We’ve been business so long that we pretty much know what we are going to need so we only order from KR twice a year, 2 big orders.
We never order online, we call. I want to know if they have in stock or not.
