Triom: Combine & Merge Orders

This app is extremely useful. We've had instances where someone places a follow-up order shortly after their initial order. Due to the shipping dimensions of our product, that follow up order can double international customers' overall shipping costs. Potentially, that's an extra $60-80 or more, depending upon the destination.

Order Merger makes it super-simple to combine orders, so we can refund the extra shipping cost. Such a deal... being able to merge 5 orders or less, per month, free of charge. I'm told the app doesn't affect website speed since it works on the 'back office, and not on the storefront.

Support is really fast and effective, too.

Depending upon your sales volume, you might want to choose to merge manually... at least while you're checking it out.
