Not so incredible connection

I wanted to purchase a ps4 combo from there online site but everytime i tried to add it to my cart it says i can only add one to my shopping cart i messaged them on the online chat they gave me some poor story of they can't update the website and there is no stock which i think is a poor excuse for a company that sells IT they can't update their website?! I think they use this false sales to promote there poor excuse for an online shop pathetic
