I recently tried Dunnes online deliveries. I would not recommend it after 2 tries and 2 separate problems later. For the past 2 years we used Tesco delivery and decided to try Dunnes to make use of the vouchers but unfortunately this was not worth the changeover. Dunnes pickers don't attempt to substitute items at all, they just don't deliver them. This is particularly annoying when you've ordered something as part of a deal, not only will you not get your items but you'll also get charged more for the items that you ordered as part of a deal that you won't now get. In addition, we ordered products to ensure we got 3 vouchers applied. However because of the unavailability of an item, we didn't get to the 150euro value (as the pickers didn't substitute, instead just left it out despite noting on the order that substitutions are ok) therefore we end up actually not getting the last 10 euro voucher applied and getting charged more for the order with less items than ordered. Customer service rep Chase is not at all helpful and basically told me it's not their problem. Really just don't waste your time. It's the most frustrating experience and takes all the good out of online ordering your groceries.
