Do our local vendors look at the Want to Buy threads. Many of us are posting dry good that need to be purchased new or used, yet no replys from vendors.
I acctually went through a lot of the vendors threads the other day because I just got a 150G to upgrade from my 90. Looks like a lot of the the vendors haven't posted in a while seems like they aren't that active anymore. The only vendors I got a quick response from were Gotham and Max Reef and Salt Water Critters. I was looking for bulk sand order.
Although I can't really speak for the vendors... You'd probably be better off sending them an email or PM with specific requests. Some of them sponsor a number of different forums, so they don't have the time to check in and read thru WTB threads...not because they don't want to do business!
I was in aquarium village a few weeks ago and they had several apex and accessories in stock. They said they would match bulk reef supply prices. http://www.nyaquariumvillage.com/
