The report, commissioned by MoreComputers.com, found that 93 per cent of UK users are annoyed by 'sneaky' website charges.
Hidden delivery charges provoke the most anger, with 64 per cent saying they would not buy from sites engaging in the practice.
The growing practice of so-called 'philfing' describes online stores holding back the real cost of 'extras' until the last minute.
Brian Trevaskiss, operations manager at MoreComputers.com, said: "Shopping online is without doubt quick and convenient. But this growing trend of 'philfing' is so annoying for consumers that they abandon their baskets and shop elsewhere."
The research reveals that 'free delivery' tariffs that only apply with an extra purchase or spending over a certain amount frustrate consumers immensely, as do hidden surcharges for paying by credit card.
Online shopping comparison sites are now finding it increasingly difficult to maintain a level playing field when listing prices, according to the research.
"We carefully monitor merchants for any signs of illegitimate or misleading behaviour," said Justin Sedgmond, merchant relations director at PriceGrabber.
"When we are made aware of any suspicious activity, we verify the problem and take appropriate action. We will contact the merchant, and solve the problem to make sure our customers are protected."
