Plain Electric Guitar Strings
Is your outlook on strings "the more, the merrier"? If so, you should probably start with a look at what Rogue has to offer. Their strings are bundled in packs of 12, ranging in gauge from the Rogue P8 Bulk 12 Pack 008 Plain Steel Electric Guitar Strings to the Rogue P22 Bulk 12 Pack 022 Plain Steel Electric Guitar Strings. For guitar teachers and entire bands, they definitely make it easy to stock up! But maybe 12 strings would be overkill - that's okay too. With smaller packages like the D'Addario PL010-5 Strings pack, you can dial things down a little to get a more modest string count that's better-suited to an individual guitarist or an ensemble that doesn't need changes quite so often.
Sometimes there's just no telling when you might need to replace one of your plain electric guitar strings - so having a few extras in your guitar case is pretty much standard practice in the guitar community. The nice thing about the selection here is that you can buy in your preferred amount of bulk, and specifically the gauges that you need most. Which means that you can set yourself up to never have to worry about snapped strings again, because you can always have a spare ready to take over.
