While the LG G6 isn't yet available - although it is up for pre-order at all of the major US carriers right now - Ringke has already discounted the prices of their lineup of cases for the new device. Of course, each case requires their own promotional code to get them for $4, so let's talk about each of the ones available right now.
There's the Ringke Fusion which is a bumper that will protect the LG G6 without really making it look ugly or make it bulky. Use the promo code FV62UQZS at checkout. Then there is the Ringke Air Prism, available in both clear and black to match the colors of the LG G6. This has a rather interesting design on the back, but it does give you plenty of grip. The clear version will need code NVJSG4FH at checkout, while the black one uses code PB3HSBI7. Finally, there is the Ringke Air. This is a more rugged case, and even features a dust cap, to keep dust out of the ports. This one needs code 5GUH6KPE at checkout.
It's currently unclear how long these prices will be available for these cases, so you'll want to grab them before they are gone. If you are looking to pick up the LG G6, this is definitely a sale you'll want to take advantage of.
