Wedo Charity Auctions

"Apart from letting people know when and where the auction will be, you should also provide a sneak peak of your auction items. This helps generate more intrigue for your auction, especially if you have high-end items like a vacation package.Mobile BiddingIf you plan to stage a silent auction over several days, you may want to add mobile bidding. This feature allows donors to keep bidding on your auction items without having to be at the auction site every day (which is especially convenient if your auction spills over to the weekdays). You can ask online charity auction services like Wedo Charity Auctions for help in establishing a process for mobile bidding."
