Did I get ripped off? Options

[mrgrape]

k so currently im 17 and just graduated high school
own a 95 celica gt auto hatchback
anyways when i bought the car my mechanic looked under and said the cv boots might need to be replaced so we got it for 4grand instead of 4.3
few months later when i took my car up in auto tech my teacher told me my cv boots are in bad condition and there was oil leak everywhere
after that i kept driving b.c i didnt have funds to replace it and started to notice a clicking sound...then i knew my axles were ****ed but i kept driving with it because didnt have funds
so finally i gather up the funds and take it to my mechanic
he tried fixing it on stands but it was really hard and we didnt have manual so he gave up
and i took it to wolfs foreign car service and they quoted me first for $430 on the phone
and they replaced both axles and labor for $490...
my mechanic said he could of replaced the axles for $75 each and labor for only $100
now is this normal shop price or did i get ripped off bc im young?
