How to get back to USA from Peru

so i've been searching 1 way tickets and they're way over $1000... so i'm gathering other ideas....

RT refundable ticket... expedia... approx $1000.. but refundable...
yahoo travel....

... thanks to someone from tribe.net... $500.. (EDIT: actually after taxes and such, it comes out to around $650)

received +$105.19 for return ticket refund from taca to Ecuador... (long story, have i explained it already??)

.....

Just now found that a one way ticket to miami from peru is $250 (including all taxes) on avianca... then to LAX on american airlines is another $184... totalling $434!!!!! I'm booking this tomorrow as I feel wiped out tonight and don't feel like dealing with it right now.. but it looks like i'll be coming home for just about $400... yay!!
