***Notice of Price Increase effective November 2nd, 2026*** [PDF]

Future Price Increases:

As background, Wilson Wolf intentionally maintains G-Rex in inventory with two objectives:

Match customer demand with enough excess inventory to prevent backorders
Tailor the amount of excess inventory to avoid needlessly diminishing G-Rex shelf-life.

We previously learned that providing 30-day notice of a price increase caused companies that purchase a large amount of G-Rex annually to place immediate orders for very large quantities of G-Rex. The unpredictability could have depleted our inventory position beyond expectations. Although that didn’t happen, we became concerned about the possibility. Therefore, given the significant increase in worldwide G-Rex market penetration over recent years, we tried a new approach to price increase notification that eliminated the risk.

While we have not made a final decision regarding how future price increases will be communicated, please be aware that historical trends in manufacturing cost inputs indicate that a price increase toward the end of 2027 or at the onset of 2028 is quite likely.
