The Attic Place is worse if you think Bagzaar smells musky.
I have consigned my Balenciaga with The Attic Place at a predetermined price some years ago. The consignment period was 2 or 3 months. On the 1st day after expiry of the consignment period, I called her that I will be going down to collect my unsold bag, she told me that the bag has just been sold and she will transfer the predetermined price less 30% to my bank account. When I questioned on why I am getting 30% lesser, she told me to read the fine print on the consignment receipt that she has the right to sell off my bag at a 30% discount once the consignment period is over. This was not highlighted to me once I consigned my bag to her and it was too much of a coincidence that the bag got sold off the 1st day after expiry of the consignment period. She was lucky that I did not pursue the matter and demand to see a copy of the sales receipt. This was the first and last time that I will consign my bags to her.
As for Bagzaar, my experiences with them have been positive. I would leave my bags with Cat and she would not sell them at a discount even if they are past consignment period. If the potential seller's offering price is lower, they would call up the customer to verify if he/she is ok with the lower price before selling the bag. If you do not want the hassle of selling your bags online yourself, Bagzaar is a safe place to consign your bags to but that's my opinion. The bags at The Attic Place move faster since they update their website regularly so you can to see what they have in their inventory before going down.
If you want the best price for your preowned bags, it's best to sell them on ebay than consignment shops since they will slash your bags down as much as possible to earn a hefty profit. Now I list my preowned bags on ebay instead, I may get a slightly higher selling price but I might have to wait longer to sell them off. It's ok if you are not in a hurry
Another place to try out is Bags Avenue @ Beauty World #02-01. The website is classicbags.blogspot.com. She has a fair collection of Chanels and LVs. I bought once from her when she used to operate her business from home.
