For a while I had MTB and LTB. At first I was happy with it as it gave me stuff I wouldnt normally use so it got me out of my comfort zone. I felt like I was getting a bargain because I was getting a lot of stuff for cheap. As time went on I started getting frustrated. They claimed to give you like $40+ worth of stuff but they always included something from Live Target which I feel is overpriced and sub par. So of the "$40 Value" $25 of that was one lure that was not great. The "Stuff I wouldnt use" part became frustrating as well. At first it was cool to experiment, but i eventually found it was clutter and it was "stuff I wouldnt use" for a reason. I ended up cancelling both.
I dont know what the deal is now, but it was historically $20 for like $40+ worth of stuff. I found I would rather spend $20 on stuff I want/need/would use vs $20 for $40 worth of stuff I don't want/don't need/wouldn't use.
To me $15/month is better spent on Bass University. Endless videos from top pros walking you through just about every season, condition, presentation, lure, etc you can think of. Learning from them has helped me far more than any of the tackle box deals.
