If they printed prices in the catalog, with a disclaimer about “prices subject to change without notice”, and later had to change the prices, how many people would be grumbling that Estes needs to honor the price printed in the catalog, disclaimer be damned? It’s not viable to commit to pricing a year+ in advance, many people shop online anyway and that allows them to see the current price immediately. It gives Estes some breathing room to respond to supply chain issues, etc., and seems like a pretty minor inconvenience for their customers.
