If you are as fussy as me regarding baby clothing purchases, then I have the guide for you!
I generally prefer to buy items which are NWT (New With Tags) or BNWT (Brand New With Tags) as I can be assured that they have not been used. At times I will also bid on NWOT (New Without Tags) or BNWOT (Brand New Without Tags) items, although there is more chance that these items have been worn, even for a short period of time, and the seller is trying to hide it from you! (This has happened to me before...!!) Generally, most sellers try to be as honest as possible.
The first step is to know what you are after. Search in the 'Baby Clothing & Shoes' section in 'Baby & Maternity'. Type in 'NWT', 'BNWT' or the brand name (ie Pumpkin Patch, Bonds, Osh Kosh, Fred Bare, Esprit, etc) in the search field and see what items come up for auction. You can then refine your search with the options on the left of the screen which usually say things like girls or boys clothing, sizes, etc.
If you are after something more specific, type it in the search field (ie 'Bonds Cozy Cuff') and see if anything comes up. You may have to be more general about searches if nothing shows up as sellers may not list their item with the wording you expect.
The next thing is to click on individual auctions and read the details in the listing. Make sure you scrutinise pictures to make sure you like the clothing. Read about the condition of the clothing, and also take a note of postage costs, as you should include that in the overall price you are willing to pay for the item. If you have any questions, ask the seller by clicking the 'Ask Seller a Question' link at the top right corner of the listing.
If you like what you see, click on 'Watch This Item' located below the price, auction time and postage details at the top of the page. You can then see a list of your watched items in 'My eBay' located at the top of every screen.
If you want to bid on the item straight away, click the 'Place Bid' button on the listing screen. When you type in your MAXIMUM bid (what you are willing to pay for in total), remember that this DOES NOT include the postage costs, so you may want to subtract the postage cost from what you are willing to pay in total, then put that amount in as your Maximum Bid.
What happens next will have to wait until the end of the auction!
