The part of the question that gives us the most information is that we're looking for a contrast, or a way of comparison. So imagine you want to compare a big and a small elephant, you could say :
<span>although one is big, the other one is small
one is big which is good, conversely the other one is small which is also not bad
one is big, however, the other one is small
An elephant is big. in contrast that one is small
So we see that all four of them can be used to express contrast!

People in the market can take your money. you could be buying something that really isn't worth as much as it costs.
Edited passage (corrections are in bold, everything else is fine):

Hope I was able to help! Feel free to leave a comment if you have any further questions :)
