WMT -- New RSI(2) Position

I'm hoping the market has overreacted to the AMZN-WFM merger. I'm a big customer of both Amazon and Walmart, but in recent years, I've seen more improvements in WMT than in AMZN. Prices at WMT are now frequently lower than AMZN, while AMZN used to be more competitive. And I can now get groceries (and other items) delivered from WMT. My four delivery orders this year all arrived within an hour. I haven't been impressed with Amazon Now selections, and Amazon Fresh is not available here (Phoenix).
