Our operating results are affected by the relative condition of the United States economy as many of our products may be considered discretionary items for consumers. In an economic downturn, our customers may reduce their spending and purchases due to job loss or fear of job loss, foreclosures, bankruptcies, higher consumer debt and interest rates, reduced access to credit, falling home prices, increased taxes, and/or lower consumer confidence. Consumer demand for our products may not reach our targets, or may decline, when there is an economic downturn or economic uncertainty. Current, recent past, and future conditions may also adversely affect our pricing and liquidation strategy; promotional activities, product liquidation, and decreased demand for consumer products could affect profitability and margins. Online customer traffic is difficult to forecast. Consequently, sales, operating, and financial results for a particular period are difficult to predict, and, therefore, it is difficult to forecast expected results for future periods. Any of the foregoing factors could have a material adverse effect on our business, results of operations, and financial condition and could adversely affect our stock price.
Additionally, many of the effects and consequences of U.S. and global financial and economic conditions could potentially have a material adverse effect on our liquidity and capital resources, including the ability to raise additional capital, if needed, or could otherwise negatively affect our business and financial results. For example, global economic conditions may also adversely affect our suppliers' access to capital and liquidity with which to maintain their inventory, production levels, and product quality and to operate their businesses, all of which could adversely affect our supply chain. Market instability could make it more difficult for us and our suppliers to accurately forecast future product demand trends, which could cause us to carry too much or too little merchandise in various product categories.
Additionally, inflationary factors such as increases in the costs to purchase products, acquire mineral rights and overhead costs may adversely affect our operating results. A continued high rate of inflation in the future may have an adverse effect on our ability to maintain current levels of gross margin and selling, general and administrative expenses as a percentage of revenues if the selling prices of our services do not increase with these increased costs.
