As limitações deste trabalho permitem dar continuidade à investigação, apesar da pertinência da informação recolhida. Assim, podem ser mencionadas as seguintes sugestões para futuras investigações:
Propõe-se a utilização do mesmo estudo, mas para uma amostra mais representativa da população;
Aplicar o estudo noutras técnicas de recolha de amostragem;
Não delimitar os fatores de incidência, alargando e incluindo variáveis que possam ser decisivas na influência do comportamento de compra do consumidor;
Recolher dados em diferentes épocas do ano, trimestralmente (por exemplo), de modo a eliminar-se o efeito de sazonalidade que pode influenciar a compra de alguns artigos em promoção e a poder estabelecer-se uma comparação entre as diferentes épocas do ano;
Examinar, de forma mais exaustiva, a definição de relações de causalidade entre variáveis, na análise estatística;
Acrescentar, na análise socioeconómica e sociodemográfica, as variáveis de animais e bebés/crianças, já relatadas na fase das limitações da investigação;
118
Alargar o número de promoções possíveis encontradas nos talões de compra, de dez para tantas quantas as existentes nos mesmos;
Ao fotografar o talão de compra de cada consumidor, capturar também os dados relativos ao valor total pago de artigos comprados;
Analisar a questão que foi avaliada como recordação assistida (pelo talão de compra) como recordação espontânea, de modo a percebermos o grau de atenção de cada consumidor, relativo aos produtos adquiridos em promoção;
Nos consumidores que utilizam uma lista de compras, analisar a mesma e comparar com o talão da respetiva compra, no sentido de avaliar se estes seguem exatamente o que diz na lista, ou se adquirem também outro tipo de produtos. Em síntese, desejamos que esta investigação desperte alguma curiosidade para a criação e profundidade de análise dum maior número de estudos, incidentes no tema aqui estudado.
