I'm sure there are several other vendors whom handle the items you were interested in at CW.
If you compare the shipping , to your time and mileage spent in acquiring the items, you may have a more realistic economy in reference to shipping cost.
We use Amazon because of two day prime, no hassle returns, generally good customer service, and pricing good on lots of items ( not all items!).
Our present location warrants buying online as its an hours drive to the nearest Home Depot for instance, and the local Wallyworld has many mt shelves, particularly in rv dept.
We like to buy local, however sometime the price warrants a 2day wait and the project is put on back burner.
Miley , in your case , the decision is yours to buy or not to buy from CW.
I prefer not to buy from CW as a botcott in general for their poor customer relationships.
I'm sure to get some flack on that remark.
Good luck in your shopping elsewhere.
