For people in Pattaya who don't have a car to shop large quantities at Tesco, Big C or Macro, I found this online supermarket that delivers for free for certain area-codes 20150 and around or maybe 100 bah delivery.

The prices are cheap and fresh products excellent quality. I have ordered now 3 times from them, always very good.

E.g. a tray cans or box bottles of Singha beer (24x330ml bottles) is 735baht, same as Macro or wholesale shops.
They have some nice assortment of farang products.

very handy for large quantities or more home bound older people.
