MBJ Departure Duty Free price comparison

Just back from another wonderful trip to Negril. I just wanted to post a "heads up" about the duty free stores in the airport. I checked the prices of a 1L bottle of Grey Goose and this is what I found:

Arrivals - okay - that was 8 days ago - it was in the $42-44 (USD) range - not much different than the $47 (CAD) / 2 for $89 I paid at Pearson.

Departure - the same 1L was $30 USD at Sunshine & $42 USD at the walk through duty free by gate 13 - big difference in price.

I only looked at the price of GG, but my point is to shop the duty frees to get the best price, on this one they weren't even close!
