I have never been to a LEGO Store, and I am hoping to go to one soon. I was wondering if anyone knew how much bricks cost at the LEGO Store? I want to buy some minifigs and some bricks. Do they sell the bricks by pound, or price per brick, or something else?
The most common way to buy bricks from LEGO stores is by filling up a PaB cup:
There are two sizes of cups and occasionally other containers that can be filled during certain promotions. The large cup is $15.99 USD and the small cup is $8.99 USD currently. This isn't advertized, but you can also buy bricks in the boxes that they are shipped to the store in. These are $100 USD.
LEGO stores also typically allow you to build your own custom Minifigs. These include legs, torso, head, headgear, and an accessory. These are currently 3 for $9.99 USD.
Pick-a-brick is a pretty cost effective to get bricks, in my experience. Prices will vary by your locale, of course, but I have one data point. For a 17 EUR PAB cup, I got around 100 EUR worth of bricks using BrickLink's average price. Since the average price is often above the median, and the median is not shown on the page, I instead recalculated using the price of the lowest lot with sufficient bricks (so if my cup contained 20 of part X I used the price of the cheapest X lot with >= 20 qty) an still the value was around 42 EUR.
