Spolied for choice

I had to do the shopping yesterday. Its sometime since I've been into a big supermarket to choose stuff I don't normally buy.

I was confronted with so much choice, I was confused. Its simple at small shops as there is one of what you need. But in supermarkets the array of options was beyond me...

I had to get some "baby milk formula" just as an addition to the breast milk my wife is giving. There are so many brands to choose from, which is best. How the heck should I know....?
