I recently had the opportunity to try Tackle Grab for a month.  The basic principle behind Tackle Grab is you sign up for a monthly membership ranging from $12-16 depending on how long you sign up and you get new baits in the mail every month.  Kind of like fruit of the month club, but for fishing.
  Interesting thing about Tackle Grab is that you fill out a profile, which asks you questions about the species, type and location of fishing you do most often to help tailor your tackle pack to your needs and wants.  Check out the following video to see what I got in my box.

All in all, I think the value that I received in my initial January box was worth more then the $15 box of single box membership.  I got a sample pack of two drop shot weights from Road Hog Baits, a Kahara Yajirobee 3 Blade ($15 value), some Optimum drop shot baits, and some Evolve Kompak Craws ($5) & a Yo-Zuri Pin Minnow jerkbait ($8).  So 5 things with a retail value around $30-$35.  It is all stuff I could use, not sure if I would have bought it all if I was shopping, but that can be a good thing as well.  The Optimum Baits Wacky Shads are solid, as I have used them before (comparable to Jackall pintail or cross tail shads) and I love the Evolve Kompak craws, I have actually caught smallies on the ones in Tackle Grab between filming video and posting this blog.

I guess the other unique thing, is you earn points every month for being enrolled, you also can earn points by doing reviews, referring friends and other activities, those points can be used to shop in the Tackle Grab store of additional items, either new stuff  you want to try or if you want more of the stuff you already received in your box.

Overall, if you are into trying new baits, and wanting to build your bait arsenal, this can be a pretty cool service for anglers.
