To the best of my knowledge they are owned by the same company.
Understand that they do offer a liquidation service, and as such you really need to do your homework on what it is exactly you are buying. Dealing in surplus (liquidation) can be quite rewarding over time if you get it right, however it is fraught with pitfalls for the inexperienced trader.
Communication is king, you'll never be able to ask too many questions when it comes to making sure you completely understand what it is you are buying.
I would suggest buying a much smaller load, don't jump right in and buy 10k worth of stock. Start off small and sample your stock, make sure you are happy with what you are getting, and most importantly, always bare in mind that even though you may be buying the same loads from the same seller, each load may well vary in quality.
That's the nature of Liquidation, and is why it's important to know exactly what you are buying.
I have no recommendation as to trading with this supplier or not, but I would be happy to suggest if you want to get into surplus then we have a very good liquidator here in our directory called Titan Liquidations.
Tim offers a very personal and professional service, and I know he would be happy to provide you with as much information on loads and the surplus market in general as you asked about.
Via Trading out of California is another I would be happy to recommend. Great company with first class customer service, and one of the priorities when dealing with a surplus supplier should be that they provide first class customer service.
