NEW YORK (CNN/Money) - General Motors could raise the incentive to the general public in line with the discounts it offers its own employees, according to a published report.

The discounts GM is offering in June are due to be released Wednesday. The Detroit Free Press reported recently that due to continued weak sales and growing dealer inventories, the savings offers will match what GM already offers its own employees.

GM employee discounts vary by the model, but can range from 3 to 4 percent below invoice price, according to the Wall Street Journal. That would mean thousands more in savings for buyers beyond current incentives.

GM has seen falling sales and market share in recent months. Especially since Sept. 11, it has been a leader in offering attractive incentives, such as zero-interest financing and other cash-back offers, as a way of supporting sales.

But those discounts have cut into margins on the most profitable vehicles, leaving the world's No. 1 automaker to report a steep loss in the first quarter.
