You can risk it and buy there. But be sure to check everything. Ask everything up front. Check everything ok, then pack everything back in then pay. Never let your sight stray away from that one box you packed. Put your hand on it or something. Hand the money over, and grab the box. And wait for the receipt. They want to pack the box for you in plastic bag, you say no need, just pass you the plastic bag. If they refuse, say you do not need a bag.
And everything they recommend you buy, you say don't need. "I already have". If they ask you to buy filter and some stupid "converter" lens before bringing the box, just say you think about it. Then when the box come, and time to pay, say you only have 960. Needless to say, prepare exact change. And hide all your other cash in some secret pocket. Pay first take the box, say come back later for the other stuff. Then you pop over to OP in SLS and get your filters and LCD protectors, bags etc from there.
Doesn't hurt to try. But be prepared for some confrontation if you do all this. Don't go alone. Go with 2 more guys or something. Anything not right, just walk. And do not, I say again, DO NOT, hand over any money before you have the camera infront of you, all checked and packed up. Once you hand over the money, grab the box immediately.
