Where to buy a chess set?

Depends how much you're willing to spend. If your price range is low, you should probably steal one.

If you want something to carry around you can get a 15" mousepad chessboard with weighted pieces on Amazon for about $20.

I got my chess set on Amazon. It's a Downhead Sheetham set and I bought it for approx £58 and it has served me well. I have around a 60% win ratio on it!

I have to say that there is a lot of great information in these forums with respect to chess sets and vendors. I've recently purchased 1851 chess set from chessbazaar, pieces are beautiful, flawless antiquing, gorgeous morphy knights, the most fantastic rooks I have ever held. Top quality at an affordable price (it's on sale). I just love the looks of the knight!

I've had good experiences buying sets from https://aurosi.com/ . They craft the pieces and board with really nice materials.

I got my chess set on www.alza.cz or on Amazon.

I suggest this shop, in particular for luxury sets https://www.chess-planet.com/

I have a very beautiful coil chess set. It is hand-made, made from natural stone. It is luxury and very beautiful. The stone is well-polished, without cracks, high quality. Shipping from Bulgaria. If you are interested, you can contact me via kseniyaluckyjadylady@gmail.com

I hope the Lady has the board around the right way when she plays.
