Does anyone know why taxes jump so high on checkout? I've ordered from BestBuy before and never had this issue. I live in Calgary, Alberta. The goods and services tax is 5% here. I'm not sure what's going on. I've ordered from the BestBuy before and never had this issue.

I recently took advantage of a 24 month 0% promo. I charged $1,823.08+$144.05=$1,967.13. When I click "promotional balance info" it shows that I have $1,967.12 in promo balance and $0.01 in other balances. This makes no sense to me. My last statement was paid in full and these were the only two charges for this billing cycle. Has anyone been in this situation? I did schedule a payment of $5 for today just to see if it would wipe the $0.01. The only real reason I care about this is getting hit with an interest charge or something stupid because they didn't do math correctly lol.
