Two options:

Refactor the template into the following:

  
    
      

        {{c.expiry}}
        {{c.code}}
      
     
  
 

Or store the filtered elements of the list in another instance member of the component:

this.filteredCoupons = this.coupons.filter(c => c.coEmail == this.shared.customerData.email)


     
      

      {{c.expiry}}
      {{c.code}}
