Make certain your website cart is working BEFORE you leave for the 'holiday'

Hm, good recommendation! I remember once I was going to Benidorm https://worldcams.tv/spain/benidorm/beach (it's situated in Spain) I didn't complete my site. There was a lack of functionality but it had lots of bugs. Since that time, I decided to never go on vacation while my site isn't working properly.
