How long should I wait for my paycheck?

I worked for a company and got laid off on June 14th. My last paycheck was supposed to be sent in the mail and on June 28th I sent an e-mail to the person who laid me off telling me I hadn't received my paycheck yet and verified my address. Turns out my address they had was wrong and she corrected it and sent it out on the 30th. I still haven't received it and am not sure how long to wait. The address I e-mailed her had no typos in it (I checked my sent mail) and I don't really know another reason it would be taking so long.
