Thank you for the extra info and photos, I really appreciate it! Unfortunately I don't have much in the way of experience with Nepenthes so I don't feel that I can give you any decent advice, but there are lots of members here who are fantastic with them and I'm sure they could help you out! I'm happy to help as much as I can with regards to the fly traps.
Do you know what type of soil they are potted in? If it's what they arrived in, then it might be safest to repot them in pure sphagnum moss until you can get some peat, as long as it doesn't have fertilisers in it as this will gradually burn the roots of your plants and kill them. They are very sensitive to nutrients in the soil, as well as with water, so it's important to water them using pure water (rainwater, reverse osmosis, distilled, deionised etc.). For more info about soil please see
here and, for water,
here. If you have any further questions then, obviously, we are here to assist you as best as we can!
From the photos you've shared, I can see that both fly traps need more sunlight (the dark green, broad leaves on one and the long spindly ones on the other tell me this). May I ask which State or hardiness zone you are from? (I'm assuming you're from the USA because you mentioned Lowes, but please correct me if I'm mistaken.) A lot of areas in the United States offer conditions that are safe for Venus fly traps to be grown outside in direct sunlight, as this is what they need. In the cooler months of the year (usually from Halloween to Valentine's Day), they have a dormancy period that needs to be respected in order for the plants to grow healthily for years to come -- I mention this because we're in the middle of the dormancy season, so it might be that your fly traps aren't growing overly well in part due to this natural occurrence (on top of the health problems they tend to develop when kept somewhere like Lowes). If you'd like more information about dormancy, please have a look at
this page.
Back to the lighting, Flytrapcare.com has an amazing article on lighting
here; this describes using natural sunlight as well as artificial lighting, depending on what is your preference and what is available to you. Generally speaking, these plants do grow best outside but I think there may be some on the forums who have at least attempted to grow them on a bright windowsill, with varying degrees of success. I used to grow my fly traps indoors due to mobility issues, and they were never quite as healthy as I feel they could have been, but I'm sure that we can talk in more detail about your preferences and what's available to you.
I don't want to overload you with tons of information as there is sooo much to take in but once you have the basics down, you may well find that your plants recover and start to flourish. These are very hardy plants that can handle a lot so, if the rhizome is still healthy, your fly traps should be recoverable in time.
Unfortunately one the perils of buying from Lowes is that they are often abused and left to get into a really sorry state upon purchase, but we've had members who have recovered them before and I know that you have this chance as well.
. but here are some better picks.
