Deal Details
I know the list price seems crazy, but some 3M gets really expensive. All Made in USA. I didn't see a total count, but I added it up in my head and it looks like 133 total tubes.

The 3M multi-color polyolefin heat shrink thin-wall tubing kit is sold 5 kits per case and is another quality product from 3M. Has a dielectric strength of 900 v/mil. The overall length measures 6 in.

It says there are 5 kits per case, so I guess we'll see? 3M stuff is expensive.

I've checked other sites to verify the extraordinary high regular price and it checks out. Why is this stuff so expensive? Nevertheless, I couldn't pass this deal up. Thanks OP!

You don't get 5 kits. There are 5 compartments in the kit.

Edit: I apologize, I can't count, there is 6 compartments. Don't have a clue what you'll actually get sent.

I've made a habit of only buying 3:1 heat shrink. It's nice being able to fit it over crimp connectors and whatnot and still have it shrink down far enough. I'm sure this stuff has other advantages, like durability or dielectric strength.

Regular price is $129.41 per case (see digikey, specifically listing price per case), each case containing 5 kits. Woot sent a single kit. (value = $25.89. So the saving were a measly 20%. There's not 5 compartments, there's 6 compartments. Also unsure why woot would list 48 inch, each tube is 6 inch.

Just caught your comment -- you're incorrect. Just google search the item (3M FP301-3/32-TO-1/2-ASSRTED). I was finding prices around $90 for the 133 piece kit. If you really think you can buy these for $25 per kit... then provide a link to where you can get it for $25. Once you start searching, you'll see that you're wrong.

Theyre mispriced and often incorrect. These kits are actually not available or commonly sold and discontinued carried in most supply houses so a lot of resellers previously had split these packs up not noticing the 5 in the name. You omitted the 5 thats why you got those results. But they are that price in majority of stores that still hold them. Most are special order. For instance, the largest retailer digikey has FP-301 - 350 pcs - 1 1/2", 1", 3/4", 1/2" (38.1, 25.4, 19.05, 12.7mm) for $20 or so. The refill on the other FP301 assorted kits are fluctuating in price per $.030-$1.50 per piece so the prices are all over the place. These kits arent even the ones you want for most applications. Most applications you want dual walled or single wall adhesive and 3:1 which would be for auto, diesel, marine, outdoors otherwise these for indoor applications
