NEW YORK (TheStreet) --Amazon.com's (AMZN - Get Report) shares hit an all-time high during its second annual Prime Day on Tuesday, but the company wasn't the only beneficiary of the day. It was a big day for small businesses as well, the company said.

CNBC's Kate Rogers joined "Squawk Box" to discuss several small businesses that sold their items on Amazon during its Prime Day, to see how beneficial it was. 

Local California jewelry maker Debbie Bean decided to test the exposure for the first time and told Rogers she had her best day ever, with a 700% increase over her average sales day.

Another local company out of Seattle, Rainier Winery, "saw its sales increase six times its average day during a time it calls a slow season," Rogers said. 

Finally, Madres Jewelry, participating for the first time as well, nearly doubled its average amount of daily sales, Rogers reported. 

However, despite increased success, selling on the Internet retail giant does not come cheap. Small businesses have to discount their products around 20% and pay Amazon fees to be able to sell on its site, which is around 15% depending on category. Although fees can be pricey, the exposure to the vast Amazon market helps these businesses tremendously. 

Amazon reported sales were up 30% by mid-day yesterday, in the number of small business items sold, Rogers noted.

Shares of Amazon are trading lower 0.80% to $742.20 early Wednesday morning.

Separately, TheStreet Ratings rates Amazon as "Buy" with a ratings score of "B-". This is driven by a few notable strengths, which TheStreet Ratings believes should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks TheStreet Ratings covers. 

The company's strengths can be seen in multiple areas, such as its impressive record of earnings per share growth, compelling growth in net income, robust revenue growth, expanding profit margins and solid stock price performance. TheStreet Ratings feels its strengths outweigh the fact that the company has had generally high debt management risk by most measures that TheStreet Ratings evaluated.

TheStreet Ratings objectively rated this stock according to its "risk-adjusted" total return prospect over a 12-month investment horizon. Not based on the news in any given day, the rating may differ from Jim Cramer's view or that of this articles's author.
