Hi all! 

Would greatly appreciate any feedback on my store. It is a marketplace, so I do not control everything about product details, but feel free to to destroy me about anything else😁 store link:

My biggest worries are:

  • General trustworthiness of the store look
  • Mobile experience (97% of traffic from mobile)
  • Store performance (Google speed check says it's pretty bad, but I do programming only on basic level, so looking for easy ways to patch biggest holes)

Thanks in advance!
