“Why do the Tectron brand of shoe protection require 'ground shipping' then only to 48-contigious states?
There is no such restriction on other brands of similar product, sent by USPS by Priority; unless these constitute an unnatural hazard, in which case the product may be hazardous in households with pets and small children. Even REI will send like items to HI and AK; there is a premium to these locations anyway. So the initial lower price is attractive.
Occasionally a vendor requests that we have certain shipping restrictions for their brand and we must honor their wishes, though we prefer not to limit the brands we sell. We continually review restrictions with our vendors to see if any changes can be made.
