Designer stamp and coins actually does have three rings for the Vario F and G's.
If they are advertising for the Vario F and G's, I've always received the correct three rings, and they are based in the U.S.
I recommend them for the Vario G and Vario F if one wants a three ring.
I ordered from someone else based in the U.S. for Vario F's and received four rings!
However, it looks like the Grande is only found with four rings.
[Edit: Actually, the Grande can be found with three rings in Canada. See BeeSee's note below. Thanks BeeSee for the correction.]
Unfortunately Designer stamp and coins has an error in their Grande advertisement, saying they are three rings in one part of the advertisement, and four rings in another part of the advertisement.
I left feedback with Amazon
indicating the error - hopefully it will be corrected.
