Despite Groupon’s recent woes on the stock market, new research shows that consumers are still drawn to discount voucher deals.

A survey of 1,000 consumers by affiliate network LinkShare found that 56% of people would buy from an unfamiliar brand if offered the right deal at the right time.

A further 41% said they have purchased something online they would never previously thought of buying because of a voucher or offer.

This is good news for voucher sites like LivingSocial, but the demand for discount deals has also led to some high profile PR disasters. For example, Need a Cake in Reading lost £12,000 after being overwhelmed with orders from a Groupon offer.

The popularity of vouchers also hasn’t done much for Groupon’s performance on the stock market, with 35% knocked off its share price this week.

The voucher website raised $700m from its IPO on November 4 and the share price quickly shot up to around $26 from a launch price of $20, but when the markets closed for Thanksgiving on Wednesday the share price had fallen to $16.96.

How the share price fairs long term will make interesting viewing for another web giant that is rumoured to be gearing up for an IPO in 2012.
