Go to a real camera store, tell them what you want to do and how much you want to spend. Make sure and look at their used cameras, open box models, refurbs, deals are out there if you are willing to look for them.
I have owned two Samsung cameras and know a few people who have owned them and they are not something I would recommend, maybe they've gotten better but the Samsung cameras I've used were pretty lame. I would suggest Canon or Nikon, even if it's a couple dollars over your budget because really, do you NEED the camera tomorrow or even next week? Maybe save up for a week and get something better, it'll save you money and aggravation down the road. But if you are going to stick to your budget I think you can find something a bit better than the Samsung for about the same money.
Just to show what I mean, the Canon Elph 530HS is right around the same price as the Samsung you are looking at, the size of a credit card (thicker obviously), does amazing macro down to 1cm focus distance and gets better reviews in pretty much every area that counts.
Here are a few comparisons with Canons, this site can do the same with Nikon but I'm not as familiar with their models so I've only included a couple.
Good luck finding a camera that suits your use and budget, whether it's the Samsung or something else.
