This will vary by retailer. For local business sites like Etsy, shipping often takes longer than a larger online retailer, but they'll often provide shipping estimates for every product before purchasing. Still, it's smart to shop ahead when you're looking to add customization to any gift because it takes extra time to etch on a special date or unique name. Personalized gifts are also available on Amazon, where shipping can take as little as one day. If needed, other large retailers often offer expedited shipping if in a hurry.
