I hope this isn't too late for everyone to use this. I wanted to post this a month ago but just didn't get around to it. Last year my friend made a lot of money by buying high demand Halloween costumes and then selling them on ebay. Here's how he did it. 1. Go to ebay and do a search for costumes and click the appropriate category Costumes. Now sort by "items sold" and "buy it now". Now sort by items ended soonest and scan through and find some that have sold the most over the past few days. 2. Now go to aliexpress.com and look up the ones you just found on ebay. When looking for a supplier to buy from you want to not only look for the lowest price but also for the most feedback and highest rated. Doesn't need to have the most feedback but I like to look for one with at least 100 in the past year. 3. Now just purchase them and list them on ebay. Make sure the shipping you choose will get it delivered with time for you to list and sell them. My guess is you'll need to pick a shipping method that will get it to you in no more than 2 weeks. Again I'm sorry I didn't get this out sooner but I hope this can help someone make some money this Halloween. You might also be able to find some suppliers on there that can dropship a single item to your ebay customers but that might be dangerous if you don't get one that can deliver a single item to them on time. Plus you'll need to check your profit margins. ********EXAMPLE ITEM******** Wonder Woman Girl Costume Sold on ebay in the last week between $25 and $33 On Aliexpress for about $10.58 from "ABU Children's Clothing"
