great prices, great customer services. here in NYC, you won't find most of the stuff for any less than 50% markup from kensfish.com
i ordered 2 breeder nets a couple months ago. one was missing a suction cup and i asked ken to see if he has a replacement for the suction cup. he then proceeded to send me an additional new breeder net. So basically i got a free one.
I also ordered two 200watt heaters. he sent 1 200watt, and 1 300watt. no additional charge for the 300 watt one. it might be inconvenient for some people but for me it was fine.
he also was receiving some items from suppliers for my order a few days after I placed the order. he shipped in 3 shipments in total so i get whatever items in stock the soonest. i didn't mind waiting a bit but Ken just goes above and beyond.
