Looks like you guys have much better luck dealing with T****** S***** than what I have had.
I done the 3x3 foam block thing back in Florida and when I get here, Spring, Texas, I found the nearest store and went in and asked for some foam blocks. Let me tell you, these guys at this store guard those darned things like they're GOLD! I bet I went in there 3 or 4 times trying to get them and never was able to do it. I even offered to BUY them cause one of the guys said they are under ORDERS that they CANNOT get rid of them cause they have to pay for them. So I told him, "Charge me what you have to pay, I'll be happy to pay it." NOPE!! No go on that either.
About a month later I just happened to pull in there and drive around back to the dumpster and I couldn't believe what I was seeing, there in the BIG LONG dumpster was 10 of those foam blocks! I hurriedly grabbed those blocks and stuffed them in my SUV. Grinning like a opossum, I went into the store to find that guy that has been such an A-Hole to me the times I've been in and asked nicely for them, when I did located him I asked if they had any MORE of those blocks they were planning on throwing away cause I just filled my car with the ones in the dumpster.
I could tell he was PO'ed.....I just smiled and said THANKS ANYWAY and left.
I went by there about 2 months ago and went in the back, in the fenced in area, and I came upon a stash of those block that had to be 25 feet long, by 10 feet wide and 10 feet tall. I don't know how many they had in there, it was HUMONGOUS! All those blocks and they wouldn't give me 9 of them even when I offered to pay for them.
I'm going to have to find another store soon cause a couple of mine are getting shot out. I move them around to minimize problems, but I could use a couple more.
The targets work great though.
I've also heard that DOCK FOAM also works great and can be found for cheap. Search Craigs List. I bet if you found some and explained your situation how you need exercise and such, they'd probably give you a really good deal. Lots of times they just want it out of their yard.
