Many big e-commerce retailers provide sorting options. For example, Amazon provides the following sort options:
Their default is "Featured". I'm sure they probably have some staggeringly complicated algorithm to determine which order items appear in their "Featured" sort, but for your case, perhaps initially sorting by "Best sellers" or "Highest rated" would suffice.
In your example, I may be curious what the best selling items are, so I'd sort by that. Or perhaps I'm on a tight budget and would like to view by ascending price. Or perhaps I kind of remember the name of the item and there's not a crazy amount of items in this category, so I can sort alphabetically and browse.
In any case, when you're unsure of where to start with these kinds of design decisions, I'd recommend taking a look at the big players and analyzing their choices. The e-commerce giants have put huge sums of money into how to get people to buy more things online. I do not recommend a practice of blindly copying how big companies do things, as certainly several features may be solutions for their unique niche or service, but there are many valuable things to learn from this exercise.
