When the peso/dollar go up, does the prices of goods also? (pesos, household)

My husband is obsessed with watching the exchange rate and gets really excited when you get more pesos per dollar. I have asked him, but does prices go up too? He never really answers me.

Last time I was there it was about 11-13 pesos per dollar and now it seems to be around 18. We are in a non tourist non border area so there is no need for inflation with people from US being there. I am curious more so for basic things like milk and household stuff. Thanks for any input!
