Hi!! Well, you can get princess plugs all over - online as well as at sex shops. There are typically 3 different sizes that most shops carry: Regular (small), medium, and large. If you shop online, you can get them for anywhere from $4-$10, but most of what we see at that price range seems to get shipped direct from China and will typically take about 4-5 weeks to arrive (quality can be both good or bad). If you go to a local sex shop, you can expect to pay $30-$60 for the same plugs (quality is usually good though).
Alternatively, we set up a little shop online that has all the plugs from $15-$25. We stock them and ship them from the US - usually within a business day. We assemble the plugs ourselves and look them over to make sure the quality is good, and then we package everything discreetly. We now sell both gold and silver in three sizes as well as a heart shaped plug and a compact button plug. We have even taken to stocking some accessories that a person might need when using these.
Hope that all helps you out, and we would love to help you get a new princess plug! Our store is at www.plugsandfun.com. No matter where you get one, we hope you try it out, and we hope you enjoy it as much as we do!! Thanks!
