Ah yes, I forgot that the price quote is always with gear and the discount comes from me having my own gear, whereas in the Caribbean, the price is the price and gear is extra, per piece.I've never been to the Caribbean, but I just googled 'Cozumel dive prices' and the first link gave me $500 for a 10-dive package, not including gear rental, whereas here 12800 THB for the same works out to $360 and includes BCD, wetsuit, regulator and fins, although not a dive computer. Normal prices on Tao are 1000 THB per dive, with bulk diskcounts and your own equipment bringing it down to 700-800/dive, so this is a ~50% premium.
Also, I'm Canadian and did the conversion on my dollars from the baht, saw $48+ and didn't then make the mental conversion to USD. My bad.
