Best Source for Kayak Accessories? Tracks, Flags, Ram...

I'm gearing-up a Trident 13 for fishing.   I'm trying to minimize additions to the yak until I've done some fishing,  but I need: waterproof tackle boxes,  safety flag/light, some gear tracks,  dry bags...

Is there a good online source that offers a wide selection of yak accessories?  Do they charge taxes?  Does NCKA have any working discounts?  I've managed to find many products at prices/shipping that were better than Amazon.  I'd like to do better. 

Thanks, kaz (Glen)

I've used Austin Kayak and Kayak Fishing Supplies...Amazon...

Thanks, Eddie.  I've found that a little research provides dividends.  Amazon often provides free shipping but the taxes are high in WA.  If I can find a retailer offering sale prices and free shipping,  I can beat Amazon.  Can't give everything to Bezos.  I haven't searched kayakfishing yet.  I'll give it a try. 

BTW: readers might like to try thriftbooks.com.  They offer used books at great discounts.  Cheaper, faster delivery, and the best customer service one can imagine.  Amazon cannot compete.

Try YakAttack. Their mighymount II and VISIflag are awesome. The omega rod holders are pretty cool as well as the various gear tracks they offer.

Not exactly impartial but YakGear.com is a great company with great gear.
