So stepping away from the COVID lot for a day - I found another Toronto Magic card store online which I thought I'd try out - www.facetofacegames.com. From a price perspective, slightly more expensive that 401games, but they had some MTG singles that 401games didn't. I waited for a sale on singles which brought the prices in line with 401games, and then loaded up on some cheap singles I didn't have for about $20 and a bit so it qualified for free shipping.
All in, a good first experience with the online store, and I can recommend them so far. The cards all came in great condition and I'm happy, so take that feedback for what it's worth!
