Eiffel 65 Albums!???

I am a HUGE Eiffel 65 fan. I know nearly all their songs, and I have made iron-on designs of their logos and pictures. And I was wondering where I can find the albums other than Europop. I bought Europop at a used CD store and I cannot find Contact, English Album, or Italian Album. Does anyone know what I could try? Would they be sold at Wal-Mart or something?
