The kit is $26.99 if that is all you buy:

If you spend $50 in tools you also will get $10 off with code: 9700083350531826
That would bring these down to $21.99 each
Here are some other deals (before discount) to get your cart over 50, but there are quite a few more on the site:

Apparently shopyourway will give you $10 off $50 if you do curbside pickup and some are getting freecash points/offers but I do not believe it is stackable.
