Deal: Save a massive $680 on the LG G8 ThinQ at Best Buy (new line required)

If you're looking to buy an LG flagship smartphone, the G8 ThinQ is on sale right now at Best Buy for as low as $150. However, as the title says, you'll have to add a new line or account with one of the US carriers to be able to get that cheap.

The unlocked LG G8 ThinQ is on sale as well, but you'll have to come up with $650 upfront, just $200 off MSRP. You could activate the phone with Sprint or AT&T/Verizon and get it for $550 or $600, respectively.

Still, the best deals are offered by AT&T and Sprint, but, as mentioned earlier, require customers to add a new line or account. The AT&T LG G8 ThinQ is available for $5/month for 30 months with AT&T Next, which means you'll be saving $680 when you buy the smartphone.

Or, you could get the AT&T LG G8 ThinQ for $6.24/month for 24 months with AT&T Next Every Year. Of course, both deals require new lines or accounts.

Sprint's model costs $10/month for 24 months with Sprint Monthly Installment, so you'll be paying just $240 for the LG G8 ThinQ. Keep in mind that the total savings of $600 include $120 Best Buy instant discount and $20/month carrier bill credited for 24 months.
