About Royal Mail Shipping Extension

Based on the weight of the items in the order, the destination and average parcel size, the Royal Mail shipping rates you select will appear in your checkout process for your customer to choose from. This reduces the risk of under or over charging your customers and increases sale conversion. Select the Royal Mail services you want to offer to customers. Rates are kept up to date when they change. Automatically shown in the checkout process.

We purchased monthly billing and asked Shopify to enable the features. This app works fine BUT I want to cancel my subs. Where can I do that?

— Dirty Laundry

We reached out to them and their support is knowledgable and responsive. App is very stable in our environment.

— Sand Dollar UK

I love this app and it is worth every penny. I have been using it for just over 2 years and any questions I have had over this time have been answered very quickly. I have been able to use it to set up postage for both small parcel and also large letters by setting my mail option to small parcel within the main settings and then setting up the large letter prices based on weight. Just this week...

I'd previously left a poor review as I'd been quite ignorant with regards the way the app worked, so I'd like to make amends. The app's great - just make sure you select the correct average parcel size for your goods - and the support from Matt has been excellent. He's very quick to respond and very helpful.

— The Spare Company

Great app, super easy to set up and immediately does what I needed it to do. Had one query and got a very quick response and resolution. So far, extremely pleased and hopefully this will make our postage work much better for customers. Liked the facility to add an amount or percentage onto postage to allow for packaging/handling as well. very useful.

— The Tea Studio

Works really well, especially for overseas orders where before we were quite often under charging, but now we are offering the delivery price per country depending on Royal Mail prices for that country.

— Jura Watches

DO NOT DOWNLOAD THIS APP! The app doesn't work accurately if you post your items in different sized boxes. There is no support and no way to cancel the subscription. It isn't showing up in my app list so i can't delete it but it is showing up in my active subscriptions so i know i will be charged. ABSOLUTE SCAM. I will be contacting Shopify about this to get them to remove the app for me.

— Super Dog Accessories

This might be a scam, it doesn't work and there is no way to talk to anyone and or stop the alleged monthly fee

— The Knife Store UK

Would be good but doesn't work with Basic Shopify package. This is not told to you until you have installed the app.

— Critically Acclaimed

Not happy with this ap...I have discovered everything is working out too expensive for my local customers and the pricing of everything being £10 up is ridiculous. I am having to remove it as its putting people off purchasing from me. I am delivering myself locally.

— Baby Rayne

App offers customers services from Royal Mail which are not facilitated in their country. Support when I first highlighted this took 12 days to get this reply: 'The app doesn't support different locations, shopify only tell us the weight of the parcel and the options are returned based on that.' I tried to work around this but the issue popped up again, this time after 7 days since sending my re...

— Vape Shop Brighton

Simple app, almost too simple. Very basic configuration options, with no option to specify a description for the service (e.g. to say how many days it might take to arrive). Also seems very slow - it takes a good 4-5 seconds for rates to be returned, which is a long time when you're a customer.

— Vetrition

Great but average size is a problem, customers are now overpaying for smaller parcels and now i have google merchant delivery problems

— ClareLouiseHair

This is app is good and serves its purpose but to be honest it could be sooooooo much better. It works on an average size of package rather than actual so it doesn't know the dimensions of the package you are sending just the weight and so can never be exact. I'm sure it wouldn't take too much to develop it further to perhaps take into account the dimensions of the products too and therefore produ...
