Yes - you will find prices ranging anywhere from $300ish to $500ish - but see what is included. For example, if the course is $300 but then you have to buy everything and then pay for the certification (PIC) fee - and the boat dives are not included for the OW portion, you will end up spending more. So at least make sure you know what all is included and any additional expenses so you actually know what it is costing you!
Blue XT~Sea is $450 and includes book, PIC (cert fee), equipment, private instruction, 2 days of beach dives and 2 days of boat dives w/marine park permits - no extra costs or surprises. If you want to do the e-learning before you get here, add $130 USD which goes right to PADI (I deduct our cost of the book from our fee in that case)
