The Garage Sale Trail is like a pub crawl for bargain-hunters and time is running out to register.
Almost Deceased Estate and Hoarders Paradise are among the names of garage sales registered to happen on the same day nationally — October 25.

Vicki Durant, of Beaumont Hills, is hoping to use her garage sale — Space Invaders — to meet the neighbourhood.
"I've just got so much stuff I've kept over the years and we recently cleared my parents' house as well, so we're hoping to make it a big event," she said.
Co-founder Darryl Nichols said the event started in Bondi in 2010 to tackle a rubbish dumping problem.
Now, residents use the event for many reasons — promoting sustainability, fund-raising or simply de-cluttering.
Mr Nichols said The Hills community has been supportive since the beginning. "They're definitely in our top 10 locations," he said.
So far, 25 households have registered.
"The residents have strong ideas concerning sustainability while also having large houses," Mr Nichols said.
"These two factors combined make them one of our most suitable communities."
Last year, the trail won an International Green Award. "People of all ages get involved, including families, seniors and young people," he said.
"Events like these just work when it's fun and social."
