Hi. I was just wondering if I can buy some of the prusa components

Hi. I was just wondering if I can buy some of the prusa components on a regular store or do I have to buy them online? Like for example, the printable pieces and the ramps/sanguinololu and the nema. Thanks!

Regular electronics store*

You can get some parts in the hardware store, but you have to get a lot online. You can get nuts/bolts/glue/rods/wire/wood in the shop, but all the nemas/electronics/hotend/belts/bearings you can’t really buy offline.
