First off, price and brand and quality/suitability are not all that strongly related in scuba gear.
If you limit yourself to whatever kit the shop is selling, there's a high likelihood you will wind up replacing some or all of it and spend more money in the end. Not because it's bad gear, there really isn't much actual bad dive gear out there, but because it doesn't fit you right or otherwise suit you. Sounds like they're trying to make it affordable and whatever they're selling is probably perfectly adequate quality-wise. And if the stuff all fits you and you like it, it may turn out to be a good choice, who knows? (One bad thing might be inexpensive stuff you buy at a big box store that is really intended for snorkeling, but I doubt that's what a dive shop is selling you.)
It will be more effort, but to get the best bang for your buck look at each piece individually. Mask is the most important right now, read about how to get the right fit then try on as many as you can. There are some perfectly fine inexpensive masks available but you really need to try them on. If you get a mask that fits and doesn't leak, you can be happy with that mask for a very long time. Spending $100 or more on the right mask and then spending $20 on fins and $10 on a snorkel might turn out to be the right thing to do.
Fins are another thing you can spend lots of money on, but there are some fairly inexpensive fins on the market that pretty much work just as well. If you want to save money, fins can also be a really good thing to buy used on eBay or whereever. With a little patience and effort you might score yourself some fins for $20 that are better than a lot of the stuff you can buy new for $150 or more.
As far as snorkels, I prefer one with a purge valve and splash guard rather than no "features" at all - but that's for snorkeling. For diving I really like the roll up ones that are easy to stash away in a pocket. So best depends on what you will do with that snorkel after you get certified. (Along with an awful lot of divers I don't like to have a snorkel dangling on my mask - you have to have one for class but after that people are all over the place on what they do about this seemingly simple thing.) If you're trying to save money, the cheapest plainest thing you can find is a good choice for now.
