Can I buy a Sheital in the year of aveilus my present weekday one is in a not good state
The sheital was bought on offer of a sale?
Buying a new shaitel during aveilus is problematic, since it is a prominent article of clothing. However if it isn’t new, then it would be permitted. If someone will wear the shaitel for 2-3 days, then it wouldn’t be considered new anymore and you can then wear it.
