Trying a new supplier for goodies always bears a certain degree of risks but I must say that I have been nothing but positively surprised by the team of Sunday and the quality of their products. Our first mission with them – Christmas jumpers & socks for our customers – has just been very successfully concluded and I can’t wait to hear from the team in the field about the customers’ reactions. The quality of the items is outstanding but also the entire process of picking the right items, support with the design and the Sunday Team’s patience with our lengthy and bureaucratic payment process has been truly fantastic. Big thank you and compliment and I can’t wait to get started on the next project! :)
