who are some good vendors to buy arrows from? looking for silver/enchanted or better preferably. thanks!

Vivec, the Fletcher in the Foreign Quarter Lower Waistworks appeared to have an excellent supply when I visited earlier.

awesome thanks again

That is an official plug in and not available in the standard game.

If you are on pc you can find it http://www.elderscrolls.com/downloads/updates_plugins.htm

I thought it was just the area-effect arrows, than the store?

You can get Glass Arrows from the armorer in Ebonheart, Imperial Garrison. He will always have Glass Arrow for Barter. You can get some Ebony Arrows from Hrundi, the questgiver at the Sadrith Mora, Wolverine Hall, Fighter's Guild. Hrundi has 40 Ebony Arrows.

yeah i figured out that it was a plug in after searching the canton up and down for about a half hour lol glass arrows sound like the ticket!

If you get Westly's The Markynaz, and the associated companion Gatanas, she will make you some Daedric arrows with the most interesting of materials, after spending the requisite amount of time as her loyal companion.
