This ~49% deal is back again. However, this time you can also use the May eBay coupons for additional savings!
Kinda glad I missed out on the original deal now.
Also available are the Surface Book 3, Pro X, (and that 8GB RAM AMD one that no one wants).
Use whichever code gives you the best savings. TOPITUP, PLSMAYY7, SNSMAY etc. Varies by device
