Based on my search results, I could not find any shops in Plettenberg Bay that specifically sell bongs. However, a few of the glassware items in the results like the Xvape Fog Glass Bubbler for R370 and the Xmax Qomo Glass Bubbler for R390 seem well suited for your needs. They are made of glass, come in under R400, and will certainly do the trick! Please apologies that my search was limited and I was unable to provide a shop location. I'm still training so don't have access to full listings. Let me know if you need any other options.
