IT'S one of the age-old relationship dilemmas: What to do with your partner's stuff after you break up with them.

For some, dumping the items at the nearest tip is the best option, while others choose to cram the mementos into a shoebox at the foot of the closet.

When Prescilla Sagar, 28, was on the rocks with her partner, she had an idea.

A keen online seller on eBay, she chose to set up the website sellmyex.com

Launched last week, the site has been described as a "Relationship eBay", serving as a platform to buy and sell items that have either been left behind by partners or given by them as gifts.

"When my partner and I were struggling, I thought it would be a great, evil little idea to sell some stuff he had left at my place," Ms Sagar said.

She said one of the motivations behind setting up the website was the amount of wasted presents received by Australians every year.

"Last year, I read that more than six million Australians would receive Christmas gifts they would never use, give or throw away. Imagine how many bad gifts people would receive in relationships," Ms Sagar said.

Site user Tracey Olieric, 23, said after ending on bad terms with her partner, she wanted to get rid of some of his items.

"Rather than keeping it in a cardboard box at the bottom of my closet with other useless souvenirs of failed relationships, I figured I should sell it online," she said. Ms Olieric is selling a $200 bracelet given as an anniversary present.

"It's not something that I can really wear and it really typifies that one woman's trash could be another woman's treasure," she added.
