Yeah, my WalMart only had the 10-pack. I'd rather have the 4-pack because I agree - I'm sure that would be plenty (for half the price!) JC Whitney and the other source listed on Lynx only had the 10-packs, too. Googling "Lynx Levelers" (also recommended on Lynx) produced other sources with the 4-pack, but they were all a little over-the-top on shipping. I found all that a little disappointing so I probably won't buy them now. I had snagged a couple pieces of wood a while back and stuffed them under the front seats in case of emergency while I was looking at other solutions. Now I think I'll just stick with that (for freebies.)![]()
