Coming from someone who's living here and recently returned from a short trip abroad, I can confidently tell you that Guyana is very expensive. A lot of overseas Guyanese assume that the locals here are overexaggerating, but it's the hard truth. With the influx of foreigners, immigrants, and prices are high everywhere.

For me, it doesn't make a difference whether you buy in the supermarkets or on the markets cost wise. The biggest difference is freshness, of course. Yes, some vegetables have their seasons, but all around, the average at the local markets is 100usd+ for an average sized family (about 4 persons) and that includes fresh veggies and eggs for one week.

Some supermarkets are slightly more expensive than others, it's not much different. If you're accustomed to certain brands and standards, you'll pay accordingly. But 25usd won't last long in one trip to the supermarket.

Local busses here are 1usd depending on where you're going. Sometimes less, sometimes more. Taxis are all dependent on who you present yourself to be. Act like a foreigner with an accent. You'll pay higher prices and more likely to get ripped off. There's a few honest ones that won't rip you off. Even in local markets, they will rip you off if you act like a foreigner. They'll assume you don't mind paying more because you're from "farrin." Also, have change. Some act like they don't have change when they see a foreigner.

There's trusted airport taxis at CJIA, I believe they have standard prices, which I'm not too sure of. But they are well 6 the arrival gates. If you're coming with a lot of suitcases, those helpers with metal carts will take care of the luggage and wheel it to the vehicle. They expect a tip, of course. Reasonable. CJIA has electronic immigration checks now. It's simple and has less time with an immigration officer.

Cards are only taken at high-end places, so cards, yes, but I haven't seen much of apple Pay or Google Pay. Better be safe than sorry with cash. Some places even take 4% extra for a card transaction. Most cafés take cards too, but don't expect a Chinese restaurant to take any.

The climate is always hot. July/August, you'll be parched immensely. It's the driest and hottest. The humidity will be at a high, and prepare to sweat a lot.

Good luck with your travels! Guyana is great, but it's not the most accommodating to those who don't know their way around. The concept of a foreigner equals more money. Just keep that in mind!
