A determined mother hit a road block trying to get her daughter the doll she wants for Christmas. The version of the toy that she wanted came at a much higher price. The mother was appalled the difference was black and white.

Tasha Banks went online to find her daughter a Little Mommy Real Loving Baby Walk & Giggle Doll, made by Mattel.

"I could not find it readily available online to purchase" said Banks.

Wal-Mart had the doll on sale but, Banks wanted the African-American version for her 4-year old daughter.

"I want her to have something that's a reflection of her and to make her proud of who she is," said Banks.

She wanted an African-American doll to help build her child's self image.

Unfortunately, Wal-Mart's website did not have it in stock. So, she tried Amazon.com and found a price difference between the White and Black dolls.

"Forty dollars is ridiculous," said Banks. "You could almost buy the baby twice."

Amazon.com offers the White version for $65 but the Black version costs $100.

"This is a sort of discrimination to me, just with dolls," said Banks.

Banks wasn't satisfied. So, she did some early bird shopping.

"Our local Wal-Mart had two of the little Black babies on the shelf at 7:30 in the morning," said Banks. "I was able to get that."

Banks says if she had not found the doll at the price she was seeking, her daughter would be getting something else for Christmas.

"My baby just wouldn't have gotten the doll," said Banks.

Instead, her daughter will have just want she wants waiting under the Christmas tree.

News 3 checked Mattel's website. The manufacturer offered both versions of the toy for the same price. When asked about the prices, a representative with Amazon.com stated, "prices change all the time and prices often vary on different variations of the same model number."

They cited examples like a brand of pots that had a difference of $19 between two colors and a toy learning system that had a difference of $49.20 between a version targeted at boys versus girls.

News 3 also asked a Marketing professor why Amazon.com may have priced the dolls differently. He said it is likely a case of supply and demand. If there are fewer Black dolls in stock, then the site can charge a higher price. And he said that is common with seasonal items like Christmas gifts.
