It looks like McMaster-Carr has changed the product listing so the "other" length can now only be 15 feet or more.
The minimum stock length is 10' for $44.40 + tax/shipping.
GSAddict is quoting $110 tested and returned in 2 days.
The website order procedure seems to be a bit off. Go to their website, enter the item number, click on other
, and put in any length you want. I just did a test order for 3' and 1' without problem. You can ignore the 15' requirement.
