Hi nkthen,
guess it's just like we go supermarket buy groceries like that, some things may be cheaper at NTUC while some others may be cheaper at Seng Siong... [Ok, I know I'm abit out of point here...]
It may be as you'd mentioned - source are from different suppliers - hence different in retail price. It may also be due to the profit margin that the LFSs owners seeking are different. Or maybe the operating cost of the LFSs also play a part (if 1 LFS is situated inside a BIG shopping MALL with aircon; the other is located at those neighbourhood shops - the former is more likely to sell at a much higher premium). Could it possibily be also due to the size of the Yamatoes & whether the owner had acclimated the shrimps for long? Not sure if there are 'gradings' for Yamatoes like for CRSs though... Whatever it is, the reasons are so varied & unlimited...
When I first got into this hobby & wanted to buy Neon Tetras, had gotten prices from $1 per piece to $0.20 per piece... Both fishes look the same to me, so in the end bought it at $0.50 per piece... [Only discovered the $0.20 per piece after getting mine, so went home pounding my heart] Hence, tend to ask around for prices nowadays first before getting my stuffs... Or may come AQ for recommendations or look for good deals...
Just my 5 cents...
