A 'lot' is a grouping of usually related items that are all sold together in one transaction. Often, you can get some great deals by purchasing this way. Sometimes the items are new, and other times, they can be gently used. Buying in lots is a good way to save money on items for yourself or your children or grandchildren. I've purchased lots both for myself and others in the past, and recently bought one for myself. The package arrived the other day, and I couldn't be happier. The shipping is also usually lower than it would be if you'd purchased the items individually, so there are additional savings that way.
