As already suggested, the selector you are using is incorrect, so elems is empty. Here is an alternative to scrape the price of an item.

from bs4 import BeautifulSoup
import requests

res = requests.get('https://compragamer.com/index.php?seccion=3&cate=62&nro_max=50')
res.raise_for_status()
soup = BeautifulSoup(res.text, 'html.parser')
item_name = "" #Enter item name you are scraping here
for item in soup.find_all("a"):
    if item_name == item.text.strip():
        price = item.parent.parent.find("span", {"class": "products__price-new"}).text.strip()
