Do these warrant another round of marathon postings?
I actively started collecting Singapore first day covers in 2020, and since then I have been searching for past year covers issued by Singapore Post. Not much luck until recently when I chanced upon Singapore Post selling past year covers during 12.12 Sale, and it's complete set of each year! Seizing the opportunity quickly, I placed order for these, and now I have full set of covers from 2015 onwards in my collection.
Back to the question on whether there would be another round of marathon postings. Looks likely there would be, so stay tuned!
