A "cookie" is a small data file that our site transfers to your device through your web browser that enables the site systems to recognize your browser and subsequently capture and remember certain information.

We use cookies to help us to improve your overall web experience when on our site. Cookies may enable us to remember and process the items in your shopping cart, to understand and save your preferences for future visits, to compile aggregated and anonymized data about site traffic and site interaction, and to reflect geographically accurate information regarding pricing. In some cases, we may contract with third party service providers to assist us in better understanding our site visitors. However, those service providers are not permitted to use any personal data collected on our behalf except to help us conduct and improve our business. In limit cases, we may allow such service providers to utilize aggregated, anonymized data for analytical purposes. We do not engage in "cookie swapping" or the sale of cookies to third parties.
