I don't know where he's getting those shipping estimates but I think he's really underselling the cost of shipping.

I don't know if this has been covered yet but PLM scuds are not unreasonably priced but they are crazy expensive to ship.

As an example, I just tried to ordering 1/2 gallon (the smallest amount they sell) of scuds. For them to be delivered from Minnesota to Pennsylvania, it will cost $340.

Below is the current price breakdown I'm seeing:

Your Final Total
Total For Products: $ 75.00
Shipping & Handling: $ 339.56 (to Indiana it is $307)
Tax (MN orders & pickup only): $ 0.00
Grand Total: $ 414.56

I can never justify paying 3-4x more for shipping than I do the product itself. Just know that before you buy scuds from PLM. Shipping is the real killer.

On the other hand, Goliad (who I believe sells Gammarus scuds) charges $45 for 1 culture (1000 scuds) and shipping is $50. Not great but a heck of a lot more reasonable than what PLM charges to ship
