Maybe this topic is overused, but I'll share it anyway. It will help you save money for more important things. When my friend and I first arrived, we went to a store near our house. It wasn't the cheapest, but not the most expensive either. However, when you haven't earned anything yet and have only recently exchanged your rubles, the prices seem astronomical in comparison.

Later, we found out about Walmart. You can find everything there, from groceries, clothes, and medicine to home goods, outdoor gear, and electronics. The prices are quite low. We could buy fruits and vegetables there without going broke, because produce is actually expensive, though it depends on the state. For example, I bought a t-shirt there for less than 2 dollars.

A bit later, we discovered ALDI. The prices there are very low, even lower than Walmart. The only downside is that it's not very big, they only sell groceries and household goods, and it closes at 8 PM.

There is also Five Below, which is somewhat similar. But it has more items and better quality. Prices range from 1 to 5 dollars. Unfortunately, the only food they have is candy, but otherwise: simple clothes (like pajamas), cosmetics, stationery, arts and crafts supplies, home goods, and all sorts of knick-knacks.

I can't help but mention stores, or rather outlets, like Marshalls and Ross. You can buy brand-name items there at a lower price.

And a general tip: buy things at outlets and try to shop in August or September. This is the season for sales—real sales of 50-70%, not like in Russia. You can buy good, brand-name items for pennies, save a ton of money for travel, and bring some cash back home.

P.S. And I almost forgot: buy things in states where there is no sales tax. For example, New Jersey has no tax on clothing, and Delaware has no sales tax at all.
