How to Filter Repeated Order ?

[manndaar]

Hello,

 

My question is How to Filter Repeated Order On Cart?

 

Example :

 

I go to domainchecker page & search for domain : abcd.com. If it is available I select add to cart.

 

sometimes due to slow connection speed Or network/server unavailability browsers show "SERVER NOT FOUND OR CAN'T FIND THE PAGE YOU ARE LOOKING FOR". So I cannot proceed to domain configuration page at that time.

 

So I go back to domainchecker page & again search for domain : abcd.com. it is available I select add to cart.

 

This time everything works fine.

 

But when I go to shopping cart page. I can see repeated order for abcd.com. & I have billed twice for the same domain.

 

 

Though this is not regular problem, I have noticed it only couple of times.

 

How to overcome this issue ? It looks unprofessional when you billed twice for the same product.

 

Need your help.

 

Thanks
