Internet: 3MB d/l with land-line (not VOIP) phone (100 minutes anywhere in MX) $45/month (includes phone and WiFi router)
Water: 5 gal "Crystal" $1.67
City 5 cubic meters (about 3K gallons) $5.35
Electricity: The rate is so low, it's only billed every other month. I'll let you know when I see one.
Yard man: The yard was in terrible shape so I hired a man for the day. $12.50 (which is not a "gringo price" but is considerably above minimum wage of $5.05/day)
Petrol: About $3.65/gallon
Groceries, paper goods, clothing, and more are a combination of better quality and cheaper prices. Anytime you need to witness this, just take a ride on the bus between Corozal and the New Market and watch what people bring back to Belize. Diapers, paper towels, toilet paper, shoes, clothes, and, if they think they can get away with it, food. It's quite an eye-opening experience watching the regulars prepare for inspection at the border.
Of course, the downside to suddenly having 30% more buying power is one tends to spend rather than save. Which should be completely understandable to anyone who has done without for long enough. Saving is well and good but buying that bit of Camembert, enjoying a reasonable bottle of Cabernet Sauvignon, a few slices of Prosciutto, or a pair of handmade leather sandals ($41.67 and individually made for your feet) is not a luxury but a necessary relief from privation.
No place is perfect and Mexico is no exception. Can you believe I had to make my own Ricotta the other day for lasagna? There's probably a Mexican equivalent out there, but with so many cheeses to choose from, it could be a while before I find it...
(Postscript: This will be my last direct comparison with Belize. Those still in Belize just don't appreciate being reminded of it - ain't that right GinandTonic? I'll follow-up with some more local prices in another post (sans reference to BZ) and, certainly, if you have a particular interest in some price comparisons for the Chetumal area, feel free to drop a line.)
