As a keen fly, course, sea and Carp angler I see the huge difference in prices across the board. What a producer, importer or supplier does is create a demand, the bigger the demand the more they can charge ( and not just rig-bits ). In this moderm age this demand is by name/badge. Huge advertising budgets are spent to make you more confident with a companies products, though in some cases ( No names ) the products are very poor, but it's to late when you have already shelled out your hard earned.
In the end it's down to customer choice, if you wont buy it for the price, they will have to improve the product, or reduce the price.
But beware, suppliers have a saying . .
If it aint selling lower the price, if it still does not sell double the original price and the customers will think for that money it must be good!
Don't be fooled by badges and labels,in many cases you can pick up a identical or like product from outside the angling world. And never buy a rod without trying it . . from experence. I won a very expensive fly rod years ago , , , it was pure c**p.
If you knew the cost of producing and getting some products to the shops it would make you cry ( rig-bits again, rods, line, bivvies etc,ect ).
The guys doing the least financial damage tend to be the tackle shop owners.
