Return

You can have it repaired by Apple: iPad Repair - Official Apple Support

You would return it to Costco if it is within their return policy but you could only return it to Apple if you purchased it at an Apple Store or Apple online and then only within their 14 day return policy.

If you buy a device directly from Apple, then you have 14 days to return it no questions asked. if you buy it from a retailer, you will need to check their return policy. I do not shop at Costco, so I am not familiar with theirs, but it appears that you may not be able to return a 2 month old device - but do check with them. Apple is not an option - if you have a problem though, do take it to Apple since you will be within the warranty period.
