hair color help :)

i recently dyed my hair a 6rr from goldwell.
i bleached my whole head to a copper color
then put on the 6rr.

and i juuust bleached my extensions.
sadly im low on money
is there a cheaper priced hair dye i can use
that comes close to goldwell's 6rr red pepper?
im so desperate i might even use box color :(

thanks :)
