Should i Purchase a Gift Yet

One of my best friends is supposed to be getting married in June. Him and his fiancee have already been discussing what to do if this virus continues to cause problems into June. He told me they would still get married in June with just them and the required witnesses and have a vow renewal once all of this calms down. His fiancee's bridal shower is supposed to be in April. The shower is a surprise and I am not sure my friend even knows about the shower. I barely know the bride, but I was still planning on attending and bringing a gift. I don't know any of the bridesmaids and they haven't reached out to anyone at this point to let us know if they are cancelling the shower. I already rsvp'd so they have my contact information to reach out. I haven't purchased anything yet. They registered at Amazon for like 100+ items. They also registered at Target for like 10 items and at Bed, Bath and Beyond for like 10 items so I planned on getting something from Amazon since there are more items to pick from on that registry. The item I have been considering getting wouldn't arrive for over a week. Because everything is so up in the air at this moment I am not sure what to do. I think even if the shower isn't cancelled that I probably would end up not going because I don't want to risk getting sick. I don't want to seem rude though. Any suggestions?
