NEW YORK ( TheStreet) -- On Wednesday, LivingSocial, the Groupon rival that received a $175 million investment from Amazon (AMZN) late last year, rolled out its first collaboration with the e-commerce giant: a $20 Amazon gift card for $10. About 544,000 people have signed up for the deal as of Wednesday afternoon, generating more than $5.4 million for LivingSocial.
