Hi rodrigo09,
Both have been online for several years -

Link hidden: Login to view since August 2001 and both are registered in the USA, however I failed to locate any significant feedback/review about them.
There's one comment here for homiezmusic.com but it's not related to their product/ reselling program - Link hidden: Login to view
I will emphasize our advice on using safe payment methods such as credit cards/Paypal, as they provide a chance for you to claim your money back if anything goes wrong. And please note that SaleHoo does not guarantee the safety/reliability of any supplier outside of its directory.
Let's wait for the others who may have feedback about this companies. :)
