I sent a 489 suregrip unit via FedEx freight due to the weight, just under 110.I just ordered last week a Mopar 8 3/4" (8.75) Nodular Iron 489 Casting 489 housing for 275.00 and the shipping was 100.00 smackers . I said oooh it will be here fast. I figured that cost would be next day or 2 days but nope it the slow shipping freight. Add those 2 together and now you have the full price.
I deal with shipping items across the county for work every day, even with our commercial shipping discount, we are still paying over double what we were when I started here in August 2021. We’ve had 3/4 of our contractors break their shipping contracts with us because those contracts were actually causing them to ship at a loss for us.
Cass aka Dr Diff is much smaller than us. And we aren’t that large ourselves, just do enough to qualify for the first tier shipping discounts. His rates aren’t set by him, like Mancini’s and others small time shops.
