The answer to this question is a little murky. Some sources say that Family Dollar does not participate in Black Friday, while others say that they do.
The truth likely lies somewhere in between.
On the one hand, Family Dollar has made it clear that they do not plan to participate in the massive shopping event that takes place on Black Friday. This is likely because Family Dollar is not as well-known as some of the other big-box retailers, and they may not be able to afford to lose sales on this day.
On the other hand, some sources indicate that Family Dollar may still participate in Black Friday, but they may do so in a more limited way. This would likely involve selling lower-priced items that are not typically found on Black Friday.
This would allow them to attract more shoppers, but it may not result in as much of a profit.
