Groceries today; Maddy should appreciate that I included some treats for her. Now if she would just keep out of my treats (she got into the butter tarts last time, before I'd had a chance to even try them).
Which websites do you use to find the bookstores? I found some cool indie type used book stores online, but from what i remember shipping to canada usually didn't make it worth my time.
There's also Book Depository and check out Amazon Marketplace. If you go there, I recommend paying careful attention to the % of satisfied customers; anything less than 90% is iffy (indicates they've had a lot of problems). You pay in Canadian funds, shipping is usually reasonable, and my other recommendation is to only consider books that are listed in Good, Very Good, Very Good Like New, or New condition.
If you buy from a Canadian seller you'll have to pay GST (and possibly whatever the provincial sales tax is in Ontario). If you buy from an American or UK seller, you won't have to pay GST (shipping time will be longer, though, and some European sellers won't ship to Canada during the pandemic).
There's a nice independent book store in Edmonton, called Audreys. I was there in person once, almost 40 years ago, and later bought one of my Classical History textbooks from them (back when COD deliveries were a thing; I couldn't get it locally). I don't remember if it was Tacitus or Suetonius I bought.
Anyway, I sent an email to ask if they do mail order outside of Edmonton (saw a couple of intriguing items on the website). Hopefully they'll get back to me tomorrow.
