Expensive, lack of housing so rent is sky high, close to Mexico (thats good and bad). Weather is awesome, lots of big titted girl (mostly silicone) with big hair and attitudes. Some nice clubs here and there.
Foods a killer sometimes. Learn to use coupons and check the sales sheets....
$3.79 gallon of milk
$2.09 dozen of eggs (Savon has them for.99)
$2.99 chicken breasts
San Diego Gas & Elextric rapes you monthly for power.
Average 2 bedroom apt will run you between 650.00 - 1,000 per month.
Get renters insurance - even if you live in a gated community.
Good luck.
