Costs are costs and they have been going up a tick at a time for many reasons.
It's great if you shoot at a club who has zero utility costs because they're paid by some benefactor, who owns their land, has no property taxes, zero facility maintenance, 100% volunteer pulling & scoring, target loading, clean up and trash disposal; in other words zero costs. I know no such club.
When cost go up they must be passed through to the end user. Some businesses and clubs alike make the mistake of trying to hold prices in check when costs are rising to apease their customers and then find themselves in a pickle because they're forced to raise prices most times by a large percentage.
A club who raised a round by $0.50 when a case of targets were raised a $1.00 may have found other costs have risen to the point where a price increase was long over due based their on overall costs. Pricing is always based on costs.
