How to advertise sale for valentines ?

[Bgrdesign]

I did a coupon, is that all I need to do or is there more things I should do to promote a sale?

If you are offering discounts to select group of people, then coupons are the right way to do that.
However, if you want to offer discounts to anyone visiting your store, then you should place a few items on sale and consider setting up sets to offer discounts for purchase of multiple items.
