Replacing our 14 year old smoke alarms in the house (5 in total) due to upcoming baby. Found what seems to be a pretty sweet deal at Home Depot for new version of direct replacements for what we need (Replacing Model 1275). 6 pack for $43.20, which is $7.20 a piece! Was able to get free shipping automatically also.
These are Kidde i12040. Amazon has them for $13.50 each.
20% off deal is only through April 30th (tomorrow)
