Sales Tax
For shipments to Indiana addresses, we are required by State law to collect 7.0% Sales Tax.


We stock over 97% of the items on our site and ship from our distribution center located in Indianapolis, IN.  Most, but not all orders that are placed in the morning will ship the same day.  Whether or not your order ships the day you place it depends on the volume of orders we are processing and availability.  If you must have same day shipping, please give us a call so we can double-check availability and get your order out the door (866-764-9900).  1 PM is the cutoff for any same day shipping requests.

At this time, we ship ONLY to the continental USA, Hawaii, and Alaska.  Freight shipments or shipments of large items to Alaska or Hawaii will be quoted on a case-by-case basis.

WE DO NOT SHIP to Canada, Puerto Rico, US Virgin Islands or any international locations.
