Frequently Asked Questions

What should I watch out for when selling or consigning luxury items?
In the luxury resale and designer handbag consignment market, the biggest traps are unclear offers and unrealistic prices. Some buyers may give a very high online quote, without clearly saying whether it is a cash buyout price, consignment price, store credit or shopping voucher. Once you arrive in-store, the price may be reduced heavily because you have already spent time travelling there.

Another common issue is an inflated consignment price that is above the real market level. It may sound attractive at first, but if the item is priced too high, it may sit unsold for weeks. After the seller loses patience, they may be pushed to accept a much lower price later.

At SW3 Boutique, our direct buyout offer is a real cash offer. For consignment, we aim to suggest a realistic market price that gives the item a genuine chance to sell, not just a high number to attract the item. If you are already in another store and receive an actual inspected cash offer, you can WhatsApp us before accepting it. We can review it and try to match the highest genuine cash offer where possible.
How fast can I get paid?
After final condition, authenticity and ownership checks, we aim to arrange payment within 20 minutes. Payment timing may depend on bank processing, item value and any extra verification required.
Do you offer both cash buyout and consignment?
Yes. Direct buyout is for sellers who want fast payment. Consignment may be available for selected high-value items if you prefer a higher target return and are willing to wait for the item to sell. For consignment, we aim to suggest a market-realistic selling price rather than an inflated price that cannot realistically move.
Will you pay the same price as the online quote?
If the item condition, accessories and details match the photos and description you sent us, we aim to honour the quoted price. If there is undisclosed damage, missing accessories or condition difference, the final offer may change.
Can I bring another store's offer?
Yes. Please bring an actual cash offer after another store has inspected your item. You can also WhatsApp us while you are still in another store, so we can review the offer before you accept it. We will try to match the highest genuine cash offer where possible, but price matching is not guaranteed.
Can I sell by post from outside London?
Yes. You can sell by post from Manchester, Birmingham, Liverpool, Leeds, Glasgow, Edinburgh, Bristol, Oxford, Cambridge and other UK cities. Please contact us first and only send your item after receiving and accepting a preliminary quote. Once posted, please send us the tracking number immediately. For safety, we currently only accept Royal Mail Special Delivery for postal selling.
Online quotes are preliminary and normally valid for 48 hours. Final offers depend on condition, authenticity, accessories, proof of ownership, market demand and final inspection. Consignment is subject to item approval, agreed pricing and final sales terms. For postal selling, please only send items after quote agreement and provide the Royal Mail Special Delivery tracking number once posted. Brand names are used only to describe the items we buy and sell. SW3 Boutique is independent and is not affiliated with, authorised by or endorsed by these brands.
