What is the best app to buy and sell used stuff in St. Catharines?
Most local deals in St. Catharines happen on Facebook Marketplace, Kijiji and Craigslist (niagara.craigslist.org), while eBay, Mercari and Swappa reach buyers nationwide. BuyLow AI compares them in one search, for buyers looking for the lowest price and sellers looking for the highest.
Is there sales tax on used items in St. Catharines?
Retailers and online marketplaces collect it: 13% HST. Casual private sales between individuals usually don't add tax, though rules vary for frequent sellers.
Where is a safe place to meet a buyer or seller in St. Catharines?
Pick a busy, well-lit public place with cameras. Many police departments offer marked internet exchange zones in their parking lots; call the non-emergency line to ask. Bring a friend for higher-value items and test everything before paying.
Can I flip items for profit in St. Catharines?
Yes. The usual pattern is to buy under market from local listings, thrift stores or garage sales and resell shipped to a national audience on eBay or Mercari, or locally at a fair price. Check sold prices first so you know the gap is real.
