Dude, Wal-Mart is running a 6-pack special for $5.48. You can't beat that! http://www.walmart.com/ip/Scotch-Brite-Heavy-Duty-Scrub-Sponges-Value-Pack-6-Pack/13281233?tv2=true&
You guys are cruel. I bought my wife a Morey Mach 7 for 20 bucks at a Costco. 70 bucks cheaper than at a surf shop. I'm sure there's a Costco in your vicinity. The boards will be right by those sweet 8 foot foam top Wavesports that are all the rage at my break! just kidding... seriously I'm gonna pick up another Morey just to have around.
Your best bet is either Atlantic bodyboards or ebodyboarding, no strictly bodyboard shops that I'm aware of.
I had good luck and good help at Eastern Lines in Belmar. They got creamed in Sandy but are reopening in March.
I'm not sure if you're being overly sarcastic, but I was just kidding. Every now & then, I'll take my BZ out for drunken shore pound. My girlfriend will float around on the sponge too - when she's not using it to clean the dishes. Let's make Thursday great.
There is no bodyboarding only shops any more on the East Coast. There used to be a handful of them. I've heard Brave New World has a selection of boards. Can't verify.
Forgot to insert My Sarcastic Emoticon. No, I'll sponge too when I think I might take a surfboard (My Own) to the head from trying to rehydrate with beer. I was serious about the 20 Buck Morey's @ Costco though.
That's your best bet. Bob at Atlantic and Jay at ebodyboarding are both super helpful and really good people. Go with atlanticbodyboards.com since you're in NJ.
