check the garden section of walmart.  they have 10 packs for $2.88 out by me.  
Might ask the manager if they will discount.  Hit him with inventory costs till spring don't make it worth to hang onto.  "wink".
I generaly get about 8 arrows from a pack or more.  Some whole packs work out and in other packs I either get a buggy one or two or one or two is like a 15# tiny thing.
