Even if I were able to reregister at this time, would the discount be accepted?
Let's say I was able to register once again at this time. Even so, would I be able to use the discount?
ご質問ありがとうございます。
それでもは英語にすると「even so」と言えますが、この場合「Even if」の方が良いと思います。
まず、「Even if」の例文：
Even if I were able to reregister at this time, would the discount be accepted?
また、「Even so」の例文：
Let's say I was able to register once again at this time. Even so, would I be able to use the discount?
「even so」は正しくないわけではない、けど丁寧的に「even if」の方が良いと思います。
ご参考になれば幸いです。
Can I get a discount this time even though I was a member before?
If I become a member again, can I still get the discount?
