I've bought on Chairish in the past with no problems; bought an antique vase for $150 and an antique chair for $2,500. Recently I saw another antique chair hat I liked and used the "make an offer" option. I did so, then realized that the height of the seat made the chair impractical for use as a desk chair. I contacted the seller, asked to cancel my offer, got no reply. I then discovered that the amount of my offer - over $800 - had been deducted from my bank account and was marked as "pending"! I went to the Chairish site, read the "fine print", and sure enough, this is what they do when you make an offer. I was used to making offers on eBay - if accepted, YOU make the payment, and YOU choose the method of payment. Not in Chairish, they use the card that you've used before and just take the money. I sent two more messages to the seller, got no reply, finally called Chairish, and a rep canceled the offer for me and I got an email to that effect. Problem is, information on the Chairish website says that if an offer is canceled, you get an IMMEDIATE refund. It doesn't say "in three business days", it says "immediate". It's now been three days, still no refund, and when I call Chairish I get a message saying, "We're really busy right now, please leave a message and don't all back!" I can't access my money, I can't reach the seller or Chairish. My bank said they would step in in another three days so I'll get my money back, but I'll never make an offer again on Chairish. They take your offer, add tax and shipping, then TAKE that amount from your bank account, without even asking if you prefer to pay using a different method, and you can't of course reach anyone.
