There are many large vendors for commercial 'store fixtures'...and most of them are now doing a lot of 'on-line' business. Shipping is going to be expensive no matter who you buy from-because most standard 'grid' assemblies are too heavy or too large for UPS and go by truck. First check your local largest city yellow pages for 'store fixtures' ....if you can find one close enough the normally will deliver on their own truck. Don't go simple by price-a local dealer might charge more than an on-line or out of state dealer, but if you don't pay freight-that really adds up. We buy most of our store fixtures through closeouts-chains shutting down, etc. and cleaning out their local spot. Also, check out 'behind' your area 'box' store-there is constantly new displays coming into Walmart, Kmart, etc. and the stores don't pay for them- the vendors do, so the other displays go into the dumpster. Kmarts right now are cleaning out by the truckload to make room to move Sears in. Word of caution, check with the store manager first before 'dumpster diving' and get permission! Roland
