Thank you all a bunch. And yes , before deciding to check here and make a post, I did try sending the creator both a notecard and an IM, as well as trying redelivery, and looking around for and asking if they had their own store related redelivery system in their store that I was in when I made the purchases. Yet, I wanted to ask here, just in case they never get back to me or it happened again in the future and I could have another solution. Also, I believed that I had the option to automatically accept items on, but I guess I didn't or there was an issue that hadn't recognized. But, I never declined it or anything of the sort. It literally never popped up on my screen but the nearby chat and the pop-op on the other side of the screen mentioning payment, did confirm that the transaction did go through and the linden paid was removed from my balance. So, they definitely went through, only the option to keep the items didn't pop up on my screen, in that moment, for either. This is the first time the option hadn't popped up, on my end to keep the items I bought. Thank you all again. I appreciate the support.
(Update: The creator just got back to me about my notecard and message that I sent prior to addressing the matter here. They were kind enough to send me the items I had been missing. I'd like to thank those who had taken the time to respond to my post, once again. I appreciate the help!)
