We asked high-growth jewellery brand Annoushka and Tryzens, one of the leading Salesforce systems integrators, about their experience integrating the Harper SfCC cartridge.

"My concierge was lovely and efficient, texting me to say when she was coming, then processing payment and giving great fashion insights all at a social distance. By trying on pieces at home, you don't need to guess if that top works with your jeans as well as your trousers - you can try it. And there are no queues at the post office for returns. An excellent service: time efficient, caring, and easy."

"This is the future of shopping! An immaculate and faultless service: the choice of different sizes and colours to try at home with own wardrobe and only pay for what we keep, returns gone straight way . Delivered on time , completely hassle free by a super friendly and competent concierge. It’s a total winner!"

"Pleasant, helpful concierge. Love the delivery service as it allows me: - to try on styles at home & quickly - to pay for what I buy rather than have to get refunds - to not have to package up & go to a pick up spot, then check it gets back to the warehouse etc - to involve my husband in what I’m considering"

"Harper is honestly the best thing since sliced bread. I worked long hours and having a charming, personalised shopping experience at the weekend is a superb pick me up. The assistants are helpful, funny and such a pleasure to interact with. I love love love this service!"

"This was my first time using Harper and I am so impressed. I was able to order and try on so much more than I normally would which enabled me to order multiple sizes and have the opportunity to try different styles. My concierge arrived on time, she was super professional and friendly, the clothes were well presented and I didn’t feel any pressure to make purchases. I would just love for Harper to represent more of the brands that I regularly use."

"Brilliant shopping experience without having to leave the comfort of my own home! Great to be able to have a one hour delivery slot, to try items on at home and to have items that were unsuitable returned and to be charged only for items I decided to keep! No annoying returns to deal with or waiting for refunds!"

"This is the first time I have used a concierge shopping service and having used Harper. I would definitely use them again. I love the fact that somebody comes to your house, will give you advice when asked and that one doesn’t have to pay up front for items that one knows will be sent back such as ordering in two sizes etc. Brilliant idea and excellent service."

"Using Harper to bring a handful of clothes to you door makes it so easy to try different sizes at home and only pay for the ones that fit or suit you. Good time slots and availability. Also so much better to style with what you have already rather than what you happen to have on. I’ve used them now for Victoria Beckham and Me+Em and hope they take on more brands."

"Great experience - I picked several items, in a few different sizes, and was able to pick a convenient date and time to try-on at home. The time was set in a 1 hour slot so no waiting around/ uncertainty on what time the items would arrive. The dresses were well packaged and it was great to try on and home with various shoes and accessories."

"First time using Harper Concierge, it’s a brilliant service. The ability to buy online, have someone bring them to your door, wait for you to try them on and give friendly honest advice."

"Excellent convenience service. You can order items in different sides to try at home and style with your own clothes to be sure you will wear them. Just decide what to keep and return unwanted items to your concierge."

"I’ve used before and was very impressed. Natasha brought all my clothes to my door, I tried multiple sizes and items on and was able to try them on with items from my existing wardrobe. I felt very certain about my purchases and confident I would not need to return them. Will definitely use again."

"Such an efficient and helpful solution when trying to select among online purchases. I opted for concierge assistance during my appointment, which eased my decision-making. Since I knew what was coming, I was able to prepare a couple of wardrobe items and styling accessories and quickly try on with them as well."

"Another successful shopping experience. From booking your slot to paying it’s a great hassle free experience. It takes all of the indecision out of online shopping. Not sure of your size order a choice of sizes and Harper will deal with your returns for you. Can not recommend this service enough."
