Beiler's is a country market that sells farm fresh produce, wonderfully fresh deli meats and cheeses, and other Amish goods such as baked goods and baking ingredients. The pricing is more than fair, and the quality is excellent.
Beiler's carries many products that are difficult to find elsewhere. They sell all kinds of spices in bulk, which makes them considerably cheaper (and fresher) than those you would find in a grocery store. They also have many different types of flour and baking supplies in bulk, including rye flour, buckwheat flour, wheat flour, wheat germ, buttermilk powder, baking soda and many more. All of these are priced well below what you would expect, and the quality can't be beat.
This is also a great place to shop for all of your cookie and cake decorations--they sell small tubs of all kinds of sprinkles and colored sugars and crystals, many more different kinds that you would see anywhere else. They also have bulk candies, nuts, and dried fruits.
