What’s for sale, only matters if you are buying.
If you aren’t buying, it doesn’t matter what’s for sale.
Deciding to buy something because it’s there isn’t going to entice you.
Just like your customers won’t be enticed if only one day a year you are going to give them the same thing on a manufactured day at a reduced price.
Why buy throughout the year?
The goal then is to make them buy throughout the year, not needing a sale.
