deported bro, 
Are you looking contraceptives for male or female ?

For Male: As we all know "Condom" is the best...Get a 20-30 pack from Amazon, it's cheaper than buying 3 pack from stores.

I usually do without  using anything for some time then put condom on !

For females, i think contraceptive pills are good. .. Most "Gori's" use pills.
