spazahome.co.uk review for Essential Upsell & Cross Sell

I have been trying to add a cross sell app and have tried so many dudds - BOGO apps that do not add the item to the cart. This app works beautifully as the pop up is clean and seamlessly intrigrates into my website as if it is part of shopify. It is not gimmicky like the others and it actually works. Very grateful to have found this.
