Everything has gone up, look at bow prices!
Arrows are no different, companies are getting larger, there are very few mom and pop type manufactures anymore so if you want a good arrow it is going to cost you more.
I have fletched arrows professionally now for about 16 years and I can tell you without a doubt if you want the best value for you $$ go with black eagle
The spartan arrow is their best arrow, it is very durable, it has a stainless nock bushing and stainless insert and the specs are extremely tight. The carnivore is a very consistent arrow but not as durable, the x impact is a micro, extremely consistent and very durable.
Slightly cheaper and actually fairly good is Easton Axis Pros, I have been finding them very tight on specs and extremely durable. The Easton Hexx is also very good but not as durable
These are a few of what is available if you ever need help finding the best arrow for your setup give me a call in the shop.
