About Shipping Options

Unlike the majority of our competitors we stock a lot of the equipment we sell and will provide two priced options to Ship From:

1) Ship from Manufacturer – to compete with other online dealers to drop ship from the mfg, this price is obviously lower with only shipping one time but will be subject to any lead time from the mfg currently estimated from mfg July or later pending Honda availability 

2) Ship from Patriot – to ship a 2nd time from Patriot stock and will ship at actual freight. Orders by Noon ship same day*

We always welcome phone calls to double check the mfg’s lead time and or quicker shipping options from Patriot’s stock.
