Any good tips for closing store please

I am going to close my store and just wondering if anyone has got any good tips for doing this.

 

I have read the Closing My Store and I understand that process, but I was thinking of maybe a sale, or changing them from Good Till Cancelled to 30 days etc etc.

 

Has anyone successfully had a way of doing it or is it best to just close. 

 

Thankyou
