If you're looking for major manufacturers like Tama, Zildjian, Paiste etc. you need to contact the manufacturers directly. Most major companies in the music business use the distributor model to get their products out there, and it can be next to impossible to find online wholesalers of these products as most distributors are prohibited from advertising online. Same goes for the guitar companies and associated equipment (amps, effects etc.)
