I used Merchandise as the keyword for each set separately, then used the Vigenere cipher. With that answer I put a Caesars cipher with seven and sixteen as the shift (coming up with two different codes). With those codes I put another Vigenere cipher with merchandise as the keyword. Then put another Caesars cipher but switched the shift values (the one shifted by seven was shifted by sixteen and vice versa). Those codes came up to be the exact same for each one but it is still encoded and I don't know what to do next. The ending code I got is tdzhsoktlm chlj qcrmj ifahf qqqj srnyz.
